I'm not suggesting throwing away Yhc, I'm simply suggesting a change of
front end. Currently Yhc uses the nhc98 front end, but this is proving
to be rather unsatisfactory so I suggest moving to using GHC as the
This is particularly 'not killing' Yhc because Yhc is really a back-end
modification, so it doesn't have a front end 'of its own'.

Interchangeable front ends is a laudable goal but pretty difficult to
achieve. In fact the easiest way to achieve it is for both compilers to
use the GHC front-end ;-)
