Hi,
I read the bug list, but couldn't find anything about the following bug in
Hugs version January 1998:

Prelude> :l HugsInternals

ERROR "/usr/pd/lib/hugs1.4N/hugs/lib/hugs/HugsInternals.hs": Unknown
entity "unsafePerformIO" imported from module "IOExtensions"
-- end session
This naturally leads to another question: why are there 2 modules, one
called IOExtensions, and the other one called IOExts?
Thanks,
Koen.
