The FFI simply implements C semantics and C has only a single,
unified namespace. What you're trying to do wouldn't work in C
either.

Also, I'm not sure that your quest to save a few keystrokes is
really justified. Code is more often read than written. Sooner or
later someone will stumble upon some Init() and won't find it in
the docs, without mentally replacing it with LibA_Init().

If it's that unlikely, then don't rename these few symbols.

You can't sensibly use conflicting names in C, either. IMHO your
worry is a bit more on the hypothetical side.
