luaL_checkoption	1.47	seconds
bsearch + memcmp	1.24	seconds
bsearch + strcmp	1.27	seconds
upvalue table	0.95	seconds
registry table	1.28	seconds

I only did string->enum, not the other way around. It seems that the 
extra `rawget()` makes a huge difference (at least for the no-op test 
functions), which probably also means that all those approaches should 
be fine for real functions doing non-trivial work ...
