#1617: :types <module> (or :browse! <module>) - browse plain types, not in
context, for IDEs

Component: GHCi | Version: 6.6.1
Severity: normal | Keywords:
Difficulty: Unknown | Os: Unknown
Testcase: | Architecture: Unknown
------------------------------+---------------------------------------------
currently, :browse <module> pretty prints types in context, which is good
for users but bad for tools building on ghci: types of class methods or
data constructors are difficult to reconstruct from that output.
could ghci please support a slight variation of :browse, with a plain
listing of 'name :: type' for all names, including class methods and data
constructors? since the code will be nearly identical to browseModule, the
command could be ':browse! [*]<module>' (with :b defaulting to :browse),
or perhaps ':types [*]<module>' (with :t defaulting to :type, not :types).
my haskell mode plugins for vim use the :browse output to avoid separate
calls to ghci every time a type is needed, but give incomplete types for
class methods and no types for data constructors, so this is a small
change (6.8.1?-) that would help all my users (and possibly other ghci-
based tools, as well).
