Comment (by goldfire):
OK, so to summarize:
* You request that `:info T` print only those instances for which the use
of `T` is visible. Naturally, this list is affected by `-fprint-explicit-
kinds`.
You mention some other ideas, but I don't think we should treat `TYPE`
specially here: if a user is asking about it, they are accessing experts-
only areas of GHC and can control the output themselves.
Do you agree that this ticket is a feature request for my bulleted
feature?
