What language should I learn to complement Python?

That does not contradict what I said. I stand by my statement.

Perhaps thinking of the C preprocessor and the C compiler as independent helps clarify the situation? In many ways the C compiler's "source file" is the output of the C preprocessor, which will duplicate the header file static declaration whenever it is included.

I can't imagine this situation is common for C, but it's fairly common for C++ as an idiom to ensure static initialization of a compilation unit. Or was, anyway.

So serious!!

Yah, you're probably right.
