I doubt it very much too.  While I made that test to strip out non-fcall 
overhead, I also made it favor the effect being produced by constantly 
calling the same function from the same scope.  Reality isn't like that.

My numbers were based on unicode.semantics=off just FYI...

I suspect optimized class fetches will help several cases too:
foo::bar();
foo::baz(foo::BLING);

Just not going to bother working on that unless it sounds worth doing to 
enough people.
