in thread how many elements in array?

Although, technically, they actually could produce the same thing, if one were to modify $[ to be 1

Update: Just a caveat that this is not recommended in the slightest :) as the docs for index say:
The return value is based at 0 (or whatever you've set the $[ variable to--but don't do that).

    RazorbladeBidet,
    While perldoc perlvar highly discourages the modification of $[, I recognize that in some very odd situation it may be the most natural way to solve a problem. In this case, it would be doing something very un-natural for the sake of being correct.

    A little bit of knowledge is a dangerous thing. If you are going to give someone a loaded gun, please give them the instruction manual too.

    Cheers - L~R
