Proposal: Generalize maybeNew

[Bas van Dijk]

Hi,

This is a tiny proposal to generalize Foreign.Marshal.Utils.maybeNew[1] from:

maybeNew :: (      a -> IO (Ptr a))
         -> (Maybe a -> IO (Ptr a))

to:

maybeNew :: (      a -> IO (Ptr b))
         -> (Maybe a -> IO (Ptr b))

so that it becomes consistent with maybeWith:

maybeWith :: (      a -> (Ptr b -> IO c) -> IO c)
          -> (Maybe a -> (Ptr b -> IO c) -> IO c)

Discussion period: 2 weeks.

Bas
