Log:
Some small steps in the direction of making GHC useable as a library:
- The ErrMsg type is now richer: we keep the location info and the
PrintUnqualified separate until the message is printed out, and
messages have a short summary and "extra info", where the extra
info is used for things like the context info in the typechecker
(stuff that you don't normally want to see in a more visual setting,
where the context is obvious because you're looking at the code).
- hscMain now takes an extra argument of type (Messages -> IO ()),
which says what to do with the error messages. In normal usage,
we just pass ErrUtils.printErrorsAndWarnings, but eg. a development
environment will want to do something different. The direction we
need to head in is for hscMain to *never* do any output to
stdout/stderr except via abstractions like this.
