Module names are used for import statements:

import mymodule;

As this is D code, it must have a valid identifier so that it
parses

import my-module;

This could probably be special cased, but you can use these names
in code

auto a = my-module.foo();

Are you subtracting 'my' from 'module.foo()?'

You can name you files whatever you want. Just include your
module name at the top (recommended anyway)

module my_module;

In this case, if you module file is named my-module, then rdmd
and other build tools that use your import information will be
unable to locate my_module.d because that file does not exist.
