-- Initial ifcxt.cabal generated by cabal init.  For further documentation,

name:                ifcxt
version:             0.1.0.0
synopsis:            put if statements within type constraints
description:

    This package introduces the @ifCxt@ function,
    which lets your write if statements that depend on a polymorphic variable's class instances.
    For example, we can make a version of 'show' that can be called on any type:

    .

    > cxtShow :: forall a. IfCxt (Show a) => a -> String
    > cxtShow a = ifCxt (Proxy::Proxy (Show a))
    >     (show a)
    >     "<<unshowable>>"

    Running this function in ghci, we get:

    .

    >>> cxtShow (1 :: Int)
    "1"

    .

    >>> cxtShow (id :: a -> a)
    "<<unshowable>>"

    .
