next year and shuddered at having to teach Foldable at the same time as

https://ghc.haskell.org/trac/ghc/ticket/10963), which allows for a way for
a user to request a specialization of a type. It all works wonderfully, but
there is a real user-facing design issue here around the default behavior
of :type and whether or not to add new :type-y like commands. I have
outlined the situation here:
> I'd love some broad input on this issue. If you've got a stake in how
this all works, please skim that wiki page and comment on #10963.
