[Haskell-cafe] Fw: Bikeshedding request for GHCi's :type

[Daniel Díaz]

I like the flag idea mentioned by Eric Seidel:

> Perhaps instead of changing the default behavior of :type or adding new

commands, we could add a flag to enhance :type's output.


Would it be overkill to have two flags, one that enabled showing the full type + specializations, and a "newbie mode" flag that only showed a few specializations?


Daniel.
