Dead right. I wasn't proposing removing the functionality, just
how to get at it. More concretely, there are two alternatives
1. Treat C-via-stdcall and C-via-ccall as two different "languages".
foreign import "C/stdcall" "gtk:foo" foo :: Int -> IO
2. Treat C as one language, but put the calling convention into the
specific string. E.g.
foreign import "C" "stdcall/ gtk:foo" foo :: Int -> IO
I prefer (1) but it's not a big deal.
