I suggest we go with a hash. It costs next to nothing and has no future

I can't imagine an app would load more than a few dynamic libraries, and the
data shouldn't need random access, should it? Would performance really be an
issue here?
I can't either. Then, I couldn't imagine a C++ application could have
50,000 global variables, until HPHP generated some. Turns out gcc does
linear look-up for global variables, which severely affects compilation
performance.
