by trying to understand how "writeIORef" works, I looked at
<x-tad-bigger>data </x-tad-bigger><x-tad-bigger>STRef</x-tad-bigger><x-tad-bigger> s a = </x-tad-bigger><x-tad-bigger>STRef</x-tad-bigger><x-tad-bigger> (MutVar# s a)
</x-tad-bigger> 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
Hans
