Need Help??

Perl is aliasing in for loops.

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

HTH! :)

So $x = 42 is as useful as 1 = 42 I don't understand this statement. I can see where an expression like `$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: `<%-{-{-{-<`	[reply] [d/l] [select]
