#1257: Bytecode generator can't handle unboxed tuples
------------------------+---------------------------------------------------
Reporter: igloo | Owner:

------------------------+---------------------------------------------------
We need to implement unboxed tuple support in ghci.
For example, with:
{{{
f :: a -> b -> (# a, b #)
f x y = (# x, y #)
}}}
we get:
{{{
$ ghci -v0 -fglasgow-exts w.hs
ghc-6.6: panic! (the 'impossible' happened)
(GHC version 6.6 for x86_64-unknown-linux):
Bytecode generator can't handle unboxed tuples. Possibly due
to foreign import/export decls in source. Workaround:
compile this module to a .o file, then restart session.
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
