Correct! Every time you use my $variable a new $variable is created that will hide the previously declared variable.

If you declare the second $variable in the same scope, you cannot access the value of the previously declared variable anymore.

If you declare the second $variable in a different scope, you cannot access the value of the previously declared variable while you are in that scope. Leaving that scope, the earlier variable will suddenly re-appear. As you will understand, this can cause all kinds of weirdness and confusion, so don't do it unless you have a very good reason for it.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
