Unbound.Generics.LocallyNameless.Embed

The pattern Embed t contains a term t.

Documentation

newtype Embed t

Embed allows for terms to be embedded within patterns. Such embedded terms do not bind names along with the rest of the pattern. For examples, see the tutorial or examples directories.

If t is a term type, then Embed t is a pattern type.

Embed is not abstract since it involves no binding, and hence it is safe to manipulate directly. To create and destruct Embed terms, you may use the Embed constructor directly. (You may also use the functions embed and unembed, which additionally can construct or destruct any number of enclosing Shifts at the same time.)
