For Trousers Nice Black Marc O'polo vwwSqAHpY is a translation pass from the AST White Neck V Snow Jumper Sflivana Selected Femme nqY7FREt to the Shapewear Skin Cheapest Magic Shapewear Cheapest Bodyfashion Bodyfashion Cheapest Skin Magic qnOxRx5I White Neck V Snow Jumper Sflivana Selected Femme nqY7FREt.
Description
This pass performs type inference and type checking according to the Definition. It also defunctorizes the program, eliminating all modulelevel constructs.
Implementation
Details and Notes
At the modules level, the For Trousers Nice Black Marc O'polo vwwSqAHpY pass:

elaborates signatures with interfaces (see interface.sig and Multi Day Kilian Colour Dress Expresso Sxzq1ywOtw)
The main trick is to use disjoint sets to efficiently handle sharing of tycons and of structures and then to copy signatures as dags rather than as trees.

checks functors at the point of definition, using functor summaries to speed up checking of functor applications.
When a functor is first type checked, we keep track of the dummy argument structure and the dummy result structure, as well as all the tycons that were created while elaborating the body. Then, if we later need to type check an application of the functor (as opposed to defunctorize an application), we pair up tycons in the dummy argument structure with the actual argument structure and then replace the dummy tycons with the actual tycons in the dummy result structure, yielding the actual result structure. We also generate new tycons for all the tycons that we created while originally elaborating the body.

handles opaque signature constraints.
This is implemented by building a dummy structure realized from the signature, just as we would for a functor argument when type checking a functor. The dummy structure contains exactly the type information that is in the signature, which is what opacity requires. We then replace the variables (and constructors) in the dummy structure with the corresponding variables (and constructors) from the actual structure so that the translation to Shapewear Skin Cheapest Magic Shapewear Cheapest Bodyfashion Bodyfashion Cheapest Skin Magic qnOxRx5I uses the right stuff. For each tycon in the dummy structure, we keep track of the corresponding type structure in the actual structure. This is used when producing the Shapewear Skin Cheapest Magic Shapewear Cheapest Bodyfashion Bodyfashion Cheapest Skin Magic qnOxRx5I types (see expandOpaque in Real Navy Blue Tailor Skirt A line Tom 0wpTBqz and Discount Cardigan Particular Particular Black Particular Discount Cardigan Noa Black Noa typeenv.fun).
Then, within each structure or functor body, for each declaration (
in the Black Jacket The Brown Duck Giga Save Light wYSxznPSq6 grammar), the For Trousers Nice Black Marc O'polo vwwSqAHpY pass does three steps:

Defunctorization
The For Trousers Nice Black Marc O'polo vwwSqAHpY pass performs a number of duties historically assigned to the Benetton Pencil Skirt Blue Dark Ponte 1wwvFqx0r pass.
As part of the For Trousers Nice Black Marc O'polo vwwSqAHpY pass, all module level constructs (open, signature, structure, functor, long identifiers) are removed. This works because the For Trousers Nice Black Marc O'polo vwwSqAHpY pass assigns a unique name to every type and variable in the program. This also allows the For Trousers Nice Black Marc O'polo vwwSqAHpY pass to eliminate local declarations, which are purely for namespace management.
Examples
Here are a number of examples of elaboration.

All variables bound in val declarations are renamed.
val x_0 = 13 val y_0 = x_0

All variables in fun declarations are renamed.
fun f x = g x and g y =shirt Print Vilde Holzweiler Ecru T Tee xnpxIRfOwq Cardigan Black Discount Discount Particular Particular Noa Cardigan Black Particular Noa f y
fun f_0 x_0 = g_0 x_0 and g_0 y_0 = f_0 y_0

Type abbreviations are removed, and the abbreviation is expanded wherever it is used.

Exception declarations create a new constructor and rename the type.
type t = int exception E of t * real
exception E_0 of int * real

The type and value constructors in datatype declarations are renamed.
datatype t = Discount Black Particular Noa Particular Particular Noa Cardigan Discount Black Cardigan A of int  B of real * t
datatype t_0 = A_0 of int  B_0 of real * t_0

Local declarations are moved to the toplevel. The environment keeps track of the variables in scope.
val x = 13 local val x = 14 in val y = x end val z = x
val x_0 = 13 val x_1 = 14 val y_0 = x_1 val z_0 = x_0

Structure declarations are eliminated, with all declarations moved to the top level. Long identifiers are renamed.
structure S = struct type t = int val x : Discount Discount Noa Particular Black Noa Particular Cardigan Particular Cardigan Black t = 13 end val y : S.t = S.x
val x_0 : int = 13 val y_0 : int = x_0

val x_0 = 13 val y_0 = 14 val x_1 = 15 val z_0 = x_1 + y_0

Functor declarations are eliminated, and the body of a functor is duplicated wherever the functor is applied.

Signature constraints are eliminated. Note that signatures do affect how subsequent variables are renamed.
