Comment (by simonmar):
Yes, the change was deliberate, but I agree it's not ideal and we should
try to fix it. I just don't know what to do about it.
The problem is that people wanted a way to say "load this file with the
interpreter only, ignore any compiled code for it". And the solution we
adopted for this was to say that any target named by ''filename'' (rather
than ''module'') would be loaded with the interpreter. But the problem is
that previously `:load Setup` would look for a filename `Setup.hs` and
load that, but that's wrong: we don't want `:load Setup` to always use the
interpreter. So I made `:load Setup` treat `Setup` as a module name,
which seems more correct. The problem is that now `:load Setup` will
expect to find a module called `Setup` when it reads `Setup.hs`, which it
often won't.
So I could probably add an exception for this case and make it work again,
but it would be ugly, and hard to document without being thoroughly
confusing. Can anyone think of a plan that is simple, easy to explain and
implement, and doesn't break existing practice too much?
