Proposal: Add (&) to Data.Function

[Yitzchak Gale]

Agreed. There does seem to be quite a bit
of support, but it's not a clear enough
consensus to add the operator to
Data.Function at this time. Therefore, the
proposal is withdrawn.

Thanks to everyone who participated in the
discussion, and special thanks to Edward for
the nice summary.
