version: 0.1
synopsis: Make functions consume Proxy instead of undefined
description: @proxied@ is a simple library that exports a function to
convert constant functions to ones that take a @proxy@
value. This is useful for retrofiting typeclasses that
have functions that return a constant value for any value
of a particular type (but still need to consume some
value, since one of the parameterized types must appear
in a typeclass function). Often, these functions are
given @undefined@ as an argument, which might be
considered poor design.
.
@Proxy@, however, does not carry any of the
error-throwing risks of @undefined@, so it is much more
preferable to take @Proxy@ as an argument to a constant
function instead of @undefined@. Unfortunately, @Proxy@
was included in @base@ until GHC 7.8, so many of @base@'s
typeclasses still contain constant functions that aren't
amenable to passing @Proxy@. @proxied@ addresses this
issue by providing variants of those typeclass functions
that take an explicit @proxy@ value.
