recursive modules in Haskell

[Simon Peyton-Jones]

| i am curious however, what is difficult about implementing recursive=20
| modules (that is, if it can be explained without getting into the=20
| technical details of GHC).

Nothing deep.  GHC is just a fairly big thing and one of its assumptions
is
that it is compiling one module at a time.  There'd be quite a bit of
chuffing
around to remove this assumption.  Nothing fundamental, but real work.
