Do you happen to know whether or not HHVM does a better job in the case of
a function being called repeatedly with different implementations of a
class/interface?
I don't optimised prematurely, but if I've got performance problems today
and getting a more sophisticated compiler/runtime isn't an option, and I
can't work around it by some other means then I don't really have a choice.
