Add ":info!" to GHCi. This shows all instances without filtering first.
The default behavior of :info is to show only those instances of
for a type, where all relevant type constructor names are in scope.
This keeps down the number of instances shown to the user.
In some cases, it is nice to be able to see all instances for a type.
This patch implements this with the :info! command.
Was there some discussion about this? The last I remember was this:
http://hackage.haskell.org/trac/ghc/ticket/5998
where we decided not to implement this because it is essentially a
random UI: the behaviour can't be described sensibly because it depends
on which interface files GHC happens to have seen so far.
There's also this:
http://hackage.haskell.org/trac/ghc/ticket/3080
which looks like a duplicate (I just closed it).
Cheers,
Simon
