Jonathan,

I'm not sure if we're talking about the same thing. You've asked:
<< If that was the case how would you ever use any type (e.g. std::string) in
more
<< than one file, it would be a different type in every file.

std::string is a rigid type defined in <string>, and if I refer it in some cpp
I should include the file where this type is defined, right? So I actually do
not redefine std::string again, I just the type defined in third file.

The my case is another. I define different types in different cpps. Functions
from one cpp can't reference types defined in other cpp, right? (note, I do not
use "extern" or something else). So struct A defined in file2.cpp should not
became an instance in file1.cpp. I'm not a guru in ISO standards, but this
particular case is one of basic things that knows everybody. Types defined in
one cpp should not appear as instance in another one.
