[Haskell-cafe] RFC: only-read-or-write-vars

Hello, I've written a tiny package for restricting access to mutable variables to be read-only or write-only: http://code.haskell.org/~basvandijk/code/only-read-or-write-vars/ This is a Request For Comments, so any comments / patches / +1s / -1s about anything are more than welcome before I upload it to hackage (sometime this weekend). regards, Bas
