Description

Utils concerning closure construction and application.

Synopsis

mkClosureSource

Arguments

:: Type

Type of the argument.

-> Type

Type of the result.

-> Type

Type of the environment.

-> VExpr

The function to apply.

-> VExpr

The environment to use.

-> VM VExpr 

Make a closure.

mkClosureAppSource

Arguments

:: Type

Type of the argument.

-> Type

Type of the result.

-> VExpr

Closure to apply.

-> VExpr

Argument to use.

-> VM VExpr 

Make a closure application.

buildClosuresSource

Arguments

:: [TyVar]

Type variables passed during closure construction.

-> [Var]

Variables passed during closure construction.

-> [VVar]

Variables in the environment.

-> [Type]

Type of the arguments.

-> Type

Type of result.

-> VM VExpr 
-> VM VExpr 

Build a set of n closures corresponding to an n-ary vectorised function. The length of the list of types of arguments determines the arity.

In addition to a set of type variables, a set of value variables is passed during closure construction. In contrast, the closure environment and the arguments are passed during closure application.
