With a module system, the library could export 'car', and another library
could import the C library with either a prefix or simply omit 'car' from
the set of imported bindings. I see no problem here.

is especially attractive, not only because it can be economically
and scientifically rewarding, but also because it can be an aesthetic
experience much like composing poetry or music."
