I would find a ForeignData extension incredibly helpful. This will be crucial if Haskell ever wants to target out of the ordinary systems.<br><br clear="all">/jve<br>

</div>Yes, it is unfortunate this is the case. my ForeignData proposal was<br>
meant to address this:<br>
<br>
<a href="http://hackage.haskell.org/trac/haskell-prime/wiki/ForeignData" target="_blank">http://hackage.haskell.org/trac/haskell-prime/wiki/ForeignData</a><br>
<br>
I am not entirely sure about the proposal as described, but I think<br>
something like it should be done.<br>
