This would be great, and could perhaps be used by other compilers as
well, but is likely to be a lot of work. Someone will need to go
through all possible Haskell error messages, probably assign an ID to
each one, and write something about the exact meaning of the error

However, this would be really really useful for beginners to find more
information. I started trying to do this with Yhc, but got bored once
I got past 10 error messages. (See
for my attempt)
