It is unlikely to ever go into Prelude as '&'. The current patch only
puts it in Data.Function.

I still maintain that '|>' and '<|' are preferable, and could go in
prelude regardless of Data.Sequence.

'&' represents conjunction in my head, and furthermore it does not
obviously relate to '$'. To remedy my concerns, I think David
Menendez's suggested '$$' should be strongly considered. This also
remedies your concern of occupying all the one-character namespace,
which makes it a stronger candidate for prelude than '&'.

And I do think that we should have a reverse application operator in
Prelude. Sitting in Data.Function it is only barely more convenient
than defining it yourself.
