It seems you are suggesting to give the possibility to set the module name
at compile time.

This would not solve my issue where I would need that the package hierarchy
is determined at runtime (because I deliver PYD files, not source files).

Now having a macro to say "use a static name" (the default, as of today) or
"determine it at runtime" is fine for me and would possibly avoid breaking
existing code.
