This true for Python too. What I have named conventionally "main module" is the module you call bud (or a saner D compiler able to find the necessary modules by itself) with. If you call bud with another name, then the "main module" becomes magically the new one.

I think that's bad.

Don't you see something bad in what you have written? You have expressed the name 'builders' two times in your command line.
So why can't the compiler, given the line:
dmd builders
define a compile variable that's true inside builders.d and false for all the other modules.
While when you compile for example:
dmd foo
is true inside foo and false for all the other modules, including builders?
