Can't have two modules with the same filename

[IsaacOscar]

When I have two files, foo.grace:

import "folder/foo" as F
F.hello

And folder/foo.grace:

method hello { print("hello") }

It fails to compile on master (due to issue #295), but compiles on the branch for pull request #297.

However it causes a stack overflow at runtime:

RequestError: error on line 1 of module foo: Maximum call stack size exceeded
  raised at module initialization at line 1 of folder/foo
  requested from module initialization at line 1 of folder/foo
  ...

Change either of the file names fixes the issue.

Yes, this has to do with the way that the compiled code references modules. It's good to register it as an issue.

I flagged this as wontfix because allowing multiple modules with the same name would require a significant re-work of the way that the compiled code functions are named. At present, they are named gracecode_‹moduleName›. A possible fix would be to name them gracecode_‹moduleSHA›, where moduleSHA is a cryptographically-secure digest of the module source.
