* milestone: Not GHC => 6.10 branch
Comment:
Note that this was reported already in #1097, but it got forgotten
probably because it has a milestone of "Not GHC" and no deadline.
The Haskell 98 report has a bug (already documented in
[http://haskell.org/definition/haskell98-revised-bugs.html]) in that the
reference implementation of the `Enum` class for `Float` and `Double` is
lazy.
I suggest we do as Don suggests, and make all the numeric types behave
consistently with respect to strictness of `enumFrom*`.
(re-milestoning to 6.10 so we don't forget)
