I do not understand the rational of the type of:
newForeignPtr :: Ptr a -> FunPtr (Ptr a -> IO ()) -> IO (ForeignPtr a)
suppose I have a c function
foreign import ccall fooalloc :: Ptr Foo
foreign import ccall foofree :: Ptr Foo -> IO ()
now I want to combine fooalloc and foofree to create a Foreign pointer
without wrapping foofree again, as in:
foreign import "wrapper" mkfoofree :: FunPtr (Ptr Foo -> IO ())
which I think counter productive - why should I import a function only to
have to re-export it again !
previouse proposals did not require this - or am I missing something ?
why should the finaliser be a foreign function ?
