When you start a new thread, your From: line is

One of your replies to Mark Hills put his address into the From: line.

I don't think that a bottom-up approach that goes through Hugs is the
best way to learn Haskell (not that going through a compiler written
in Haskell will be any better).  You're better off taking the Haskell
98 Report as the baseline.

The explanation is in the above messages of Mark Hills and myself; I
can't think of another way to express it.  Basically you put an internal
Hugs module where it wasn't expected.  Just don't do that.
