    (Downvoted because):

    It's not meaningless when the perldocs refer to For Loops and Foreach Loops. They also mention that
    The foreach keyword is actually a synonym for the for keyword, so you can use foreach for readability or for for brevity. (Or because the Bourne shell is more familiar to you than csh, so writing for comes more naturally.)
    So the correct response to : "What is the difference between for and foreach?" is "The keywords or the loop structures?"

    It's an English problem.

      You're right. Thanks for downvoting me, I deserved it.

        Not downvoting you, just the post. I have a lot of respect for many people on here, you (highly) included. People often say explanations should be given with downvotes. There's mine :)

    Can we both agree on this:

    In Perl, the keywords "for" and "foreach" are identical. In many other languages, the two words stand for two different kinds of loops

    No, only if you change that to "many languages, including Perl".

    perlsyn has a heading called "for loops", and a heading called "foreach loops". I'm going to quote that as an authority, as it was written by the only authority who really matters. Therefore, Perl has for loops, and foreach loops, and overlapping keywords. "for" and "foreach" are not the same in that sentence.

      Ok, how about:

      In Perl, the keywords "for" and "foreach" are identical. In many other languages the two keywords refer to two different loop structures. Perl supports both loop structures, but allows the use of either keyword for either structure.

        Many other languages? Could you name a few that actually have the keywords 'for' and 'foreach', and refer to two different loop structures?
