Function declarations, which declare a variable and assign a function to it, are similar to variable statements, but in addition to hoisting the declaration, they also hoist the assignment – as if the entire statement appeared at the top of the containing function – and thus forward reference is also possible: the location of a function ...
Let : be a function from a set to a set . If a set is a subset of , then the restriction of to is the function [1] |: given by | = for . Informally, the restriction of to is the same function as , but is only defined on .

In mathematics, a corestriction [1] of a function is a notion analogous to the notion of a restriction of a function. The duality prefix co- here denotes that while the restriction changes the domain to a subset, the corestriction changes the codomain to a subset. However, the notions are not categorically dual.
The above example is rejected by the type checker under the value restriction as follows. First c is given the type ( α → α ) r e f {\textstyle (\alpha \to \alpha )\ {\mathtt {ref}}} . This type is not generalized and α {\textstyle \alpha } is a free variable in the typing context for the body of the let binding.

The return value from a function is provided within the function by making an assignment to an identifier with the same name as the function. [5] However, some versions of Pascal provide a special function Exit(exp); that can be used to return a value immediately from a function, or, without parameters, to return immediately from a procedure.
