remember that `for (LIST)` localizes $_ and `while (<HANDLE>)` doesn't. Generally, for() is safer, but sometimes you want the while() behaviour. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l] [select]

That would mean I have to read the whole file into memory, and return a list of chunks. Depending on the filesize this might turn out as a bad idea ;-)	[reply]

No - each iteration returns a chunk into $_ in the for or foreach loop. One world, one people	[reply]

definitly not. `use FTest; my $test = new FTest (); print foreach $test->foo; print for $test->foo;` [download] Meanwhile in a module `package FTest; sub new { return bless {}, shift; } sub foo { return 1; } 1;` [download] That code prints "11". I you were correct that would be an endless loop.	[reply] [d/l] [select]
