the cmm pages on the wiki seem out of date

[Simon Peyton-Jones]

Simon Marlow is the man who will really know.  He's in the middle of getting to grips with Facebook but I'm sure he'll pop up soon.

In general, yes please do update the wiki; thank you.

Simon

|  Yes, there were some pretty recent (as in, not present in 7.6) improvements
|  to C-- syntax.  Updates would be much appreciated; you can probably figure out
|  what the changes are by snooping the changelogs for compiler/cmm.
