This only works when you compile one file at a time, so the compiler does not
notice the module name discrepancy. The way you build your project is very
unusual, today most D software is built with dub or rdmd.

In short: the compiler is not detecting a problem in your project as an
optimization. When dealing with packages, all modules need to have a module
statement indicating the full name of the module - even if you don't do that
and somehow get things to compile, you will likely get linking errors due to
differences in full mangled names of symbols.
