[Haskell-cafe] memorize function with number parameterized types in GHC

[Bin Jin]

Yes, but I think it's not a funtion since the function didn't use the
parameter. So maybe there is a way to make memorizing possible.

Also p2num is a general function used in number parameterized types, so I
asked this question here.
