Hi all,

We've had Control.OldException, and the new Control.Exception, since GHC
6.10.1, and since 6.12.1 using Control.OldException has given the
deprecation message
    Future versions of base will not support the old exceptions style.
    Please switch to extensible exceptions.

I propose that we now remove it from base.

If some people still cannot use the new Control.Exception for some
reason, then it could be maintained in an old-exception package.

Discussion deadline: 18 Feb 2012.
