I couldn't find any mention in the perldelta and Perldoc.org doesn't list 16.3. For loops used to have the limitation to flatten the iterated structure to a list, which resulted sometimes in unfortunate memory requirements. IIRC this was partially fixed by parsing if it's an @array or a range-operator, and acting like an iterator (ie `for (reverse 1..1e18)` remained problematic, because reverse was not detected) I'd say this is the essential hook allowing your trick of iterating an "injected" tied array. Did I miss something? Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply] [d/l]
