There's a ticket for that: https://ghc.haskell.org/trac/ghc/ticket/1257
("Bytecode generator can't handle unboxed tuples"). Fixing that would make
it much easier to use GHCi to load the compiler, and allow setting
breakpoints, make a change and use `:r` to reload etc. The ticket is closed
as wontfix however.
