Overlapping and incoherent instances

[Simon Peyton Jones]

CAN_OVERLAP and CAN_BE_OVERLAPPED?

(instead of OVERLAPPING and OVERLAPPABLE)

Or CAN-OVERLAP, CAN-BE-OVERLAPPED

That’s ok with me if that’s what you all want!

+1. I like Niklas' syntax better.  Also OVERLAPPABLE is a horrible word, OVERLAPPING sound less formidable (even though it might be slightly less accurrate).

We already get "overlap ok" in instance-related type errors, so OVERLAP_OK wouldn't be particularly alien even if it doesn't quite fit in with existing pragmas.
