Proposal for containers: Add 'lookup' function to Data.Set

[Joachim Breitner]

Hi,

given that for naive uses and users, the existence of lookup is more
confusing than helpful, I’m in favor of a name that indicates “this is
advanced foo”, a suitable documentation, and moving it to the very end
of the module documentation, as it is not a function you’d expect for a
set implementation.

The name "Pointer", though, might be a bit too low-level. Maybe
"lookupWithSharing"?

Greetings,
Joachim
