Hi -
I've got the beginnings of an API for a GUI system as follows:
foreign import ccall duma_createEdit :: IO (Ptr (Edit a))
createEdit :: IO (ForeignPtr (Edit a))
These should of course be:
foreign import ccall duma_createEdit :: IO (Ptr (Edit ()))
and
createEdit :: IO (ForeignPtr (Edit ()))
(just in case anyone else new to phantom types reads this email before
writing a GUI)
Regards, Brian.
