FRP.Animas.Miscellany

Collection of entities that really should be part of the Haskell 98 prelude or simply have no better home.

!!! Reverse function composition should go. !!! Better to use <<< and >>> for, respectively, !!! function composition and reverse function composition.

(#) :: (a -> b) -> (b -> c) -> a -> c

Reverse composition

dup :: a -> (a, a)
