Comment (by igloo):
In the HEAD/6.10 we get:
{{{
Foo/Bar.hs:1:0:
File name does not match module name:
Saw: `Main'
Expected: `Foo.Bar'
}}}
The problem is that when we go to compile Foo.Bar we first want to get its
imports, so that we know what else we have to compile first. When we hit
the pragma, we think that the module body has started, and do not parse
any more, so as far as GHC is concerned this is a module that has no
header, and thus defaults to module Main. I'm not sure how we can do
better. Perhaps returning the source location at which we decide what the
module name is would help?
