Re^4: Efficient but elegant Cross-Product iterator ?

NestedLoops allows to pass code-refs, i.e. they will be dynamically (re-)evaluated each time one loop-level is (re-)entered.

Ah, so it will create the arrays for you, cool. (Added the alternate solution to my earlier post.)	[reply]

It's also semantically different! The subs don't need to return a constant list, so each loop might restart with a new dynamic list. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]
