Hi!
I'm using the IOExts-library and want to use
modifyIORef instead of updateIORef which is marked as deprecated
(section 4.14.2 in the hslibs documentation).
Unfortunately IOExts.hi doesn't export modifyIORef. It only
exports updateIORef..
Is it safe to use updateIORef meanwhile?
bye,

let me know and I'll add it to the site. I know there are some very
good slides from Haskell courses that could be put into haskell.org.

Isn't this related to the "munging" that GHC makes use of on other platforms?
Apple's cc (actually gcc) does not accept 'asm'

A syntax to choose the active instances may be useful, too.
E.g.:
use EccenticOrd, SetCollection in exp
then in exp the instances EccenticOrd, SetCollection are known (or preferred).
This is similiar to the open syntax in Cayenne.
