okay, thanks (seems there's always a reason to look forward to the
next release, and the one after, and .. ;-).
[has there been any progress on the idea of having weekly or so
windows snapshots of CVS GHC generated automatically?]
For context: I wanted to show people in the haskell tools thread
- how easy it is these days to write a Haskell program transformation
for instrumenting source code with asserts, e.g. to get location info
for heads of empty lists :-)
- why these lovely new tools won't be used because even without
transformations they don't reproduce the source :-(
But as they can't use this in the current release anyway, I'll leave
it at that.

ago, after which people had to reestablish their access rights with
whoever holds those.
