PAST-pm's handling of assignment is about to be refactored a bit in order to support Perl 6's binding operator (:=). Yes, the generated code sometimes calls a clone when it doesn't need to -- this is going be handled by having PAST-pm keep track of which PMCs are "temporaries" and thus available for re-use instead of requiring cloning. > - The old Punie was loading a library of builtin functions in the 'main' > routine of every generated Perl 1 script.

One of the next items that will be implemented in perl6 (and may make it into PAST-pm) will be to support BEGIN/CHECK/INIT/END blocks. Thanks! Pm
