I have a file named "Object.d", in a directory called "foo". The module 
name of this file is "foo.Object". As it happens, I'm using OS X which 
uses a case insensitive file system. I also have another file, say 
"Bar.d" in "foo", with the module name "foo.Bar". When I try to 
compile/run Bar.d with rdmd as follows:

rdmd foo/Bar.d

I get a lot of errors like "undefined identifier string" and "undefined 
identifier size_t" from some modules in druntime and Phobos. If I rename 
"foo/Object.d" to "foo/Object2.d", leaving the module name as 
"foo.Object" everything works as expected.

WAT?? I thought D's module system would prevent mistakes like this. Is 
this the expected behavior? I think the issue is that "rdmd" adds a 
flag, "-Ifoo", when running dmd to get the dependencies. But the module 
system should still prevent it. It seems like the compiler uses the 
filename instead of the declared module name as the module name.

I think this is an issue with the import resolution, not module 
system. The way it is implemented right now DMD stops searching 
for object.d / object.di once it has found one. So while your 
module name is not interpreted as "object" _original_ object.di 
does not get imported and you get lot of different issues from 
missing declarations.

So it just picks the first filename matching "object" and doesn't care 
about its module name.
