convert "in class" methods to absolute straight calls into C
like void method_1... {}
void method_2() { ... method_1(a,b,c) ... }
but for the rest just leave them all dynamic-y...unless you want to have to put in a huge case statement...maybe?
I think that updating it to use correct arity and/or inlining <> calls might also be great [and possibly higher priority] optimizations, too.
even then it's a straight C call versus making an extra array and a dynamic C call--these are all in C! Probably all low priority! 1.9 compat. might be highest?
"if non opts then use the right arity" first prio [kind of--if faster] "then 1.9 or maybe direct direct local?"
