> D source file names with hyphens should be allowed, e.g., "test-bu.d".

Note that module names must be valid D identifiers. So if you have "test-bu.d"
it would need to have a separate module declaration (e.g. "module test_bu;").
This this also means that the compiler either has to try and use heuristics to
find the file on disk, or you have to explicitly pass it to the compiler.

It's implementable, but I'm not sure if Walter would ok this.
