Ok, let it be.
My optimizer will never hurt any program regardless the features it uses. 
Moreover it can do some optimization to any program (at least optimizations 
that touches only local variables and branches where no unknown code would 
had be executed). But to get the best one must either use it for complete 
code or add annotations about absent code. I'll try to make adding 
annotations as easier as possible.

If it uses them only a bit than adding annotations will not be vary hard.

Anyway, thanks for your attention and explanations !
