Is this true or am I miss understanding something?

Its more or less true , naturally named subroutines live in the symbol table (globals), my vars don't live in the symbol table

What about compile time vs runtime?

Yes, those things exist :) BeginCheckInitEndUnitcheck.pl

Um, yeah, I'd get rid of that code, esp the maths parts :) .oO( wheel? If I add multiply and divide these wheels, where is my question? )
