Make unboxed tuples more supported
Unboxed tuples (# a, b #) do not have the same features as boxed tuples ( a, b ). In particular:
-
There is no prefix form,
(#,#) a bis not equivalent to(# a, b #). We would have to define a collection of such functions in the Prelude (see Data.Tuple, for the (,,,,) functions). We'd have to do is to make the parser understand(#,,,#). -
Currently GHC does not allow
f :: (# a, b #) -> ..., but there's no real reason why not; GHC could transform them away just before code generation.
