Re^2: which loop is better

for and foreach are synonyms. there really is no difference between them:

for (@arr[0..2]) { $_++; }
foreach (my $i = 0; $i <= 2; $i++) { @arr[$i]++; }

will work just as well

Err, I don't think what you say is very clear. For and foreach are synonyms, but either of them can be used to delcare two completely different loop contructs, ie the following two lines are identical to each other `for (expr; expr; expr) block foreach (expr; expr; expr) block` [download] while the following two are identical to each other, but not to the first two lines above `for (list) block foreach (list) block` [download] Dave.

You're right that I wasn't very clear :-) I meant that the lines in my code where synonyms of the code in the post I was replying to. I meant to say that typing `for` or `foreach` has no impact on the kind of loops you can create with them. "What should it profit a man, if he should win a flame war, yet lose his cool?"
