Description

Deprecated: Use Fcf.Class.Functor or Fcf.Class.Bifunctor instead.

Overloaded functions.

Synopsis

Documentation

data Map :: (a -> Exp b) -> f a -> Exp (f b) Source #

Type-level fmap for type-level functors.

Note: this name clashes with Map from containers. FMap is provided as a synonym to avoid this.

Example
