by trying to understand how "writeIORef" works, I looked at
data STRef s a = STRef (MutVar# s a)
what is MutVar# ? (especially zhe "#" ) ? I've readed tha writeIORef
(and readIoRef etc) is used to write directly to memory places fo
implementing variables, as in example in HOpenGL used. Is this also
Haskell standard ?
Thanks for help
