Re^2: Efficient but elegant Cross-Product iterator ?

Almost, instead of code refs, you are expanding the subs to arrays before passing them.

For this simplified example the result is the same though.

Well yeah. You necessarily need to store the results of the subs somewhere, and in what else would store the results of the subs but in arrays?	[reply]

NestedLoops allows to pass code-refs, i.e. they will be dynamically (re-)evaluated each time one loop-level is (re-)entered. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]

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