Perl is aliasing in for loops.

So $x = 42 is as useful as 1 = 42

HTH! :)

    I don't understand this statement. I can see where an expression like $x = 42 might be useful, but 1 = 42 can't possibly be useful because it won't compile.

    Update: Or do you mean "if $x is aliased to a literal value (e.g., 1), $x = 42 is equivalent to 1 = 42"? (Update: And specifically WRT to the for-loop here? I didn't look back far enough. :)


    Give a man a fish:  <%-{-{-{-<

      > And specifically WRT to the for-loop here?

      yes, sorry I'm getting lazy these days.

      I have the feeling I'm heavily repeating myself over and over.
