there is common proposal that i support. example of its use:

I think that's too safe-looking. Anything that translates to something involving unsafe* should be tagged with 'unsafe' somewhere as well. Also, as unsafe* is still compiler specific, I think a pragma is probably most appropriate: {-# GLOBAL-MUTVAR #-} i :: IORef Int i = unsafePerformIO (newIORef 1) -- -David House, dmhouse@gmail.com
