I agree. I've no strong opinions on how it's done, but I do believe that it's *very* important that subroutine calls be as fast as possible (and significantly faster than perl5). This must be a priority. To my mind that means that a subroutine should be responsible for setting up whatever _it_ needs (and ideally only what it knows it needs). Then the sub code is encapsulated and can be changed at runtime. Tim.
