Calling local on a list of variables modifies the values of those variables to be "local" to the current block, and to any subroutines called from within that block. It does this by saving the value of the variable before you called local, then restoring the value after the block has ended (or some variation on this; it may be more complex. :)

Take a look at perlsub (Temporary Values via local()) for a better explanation.

Sure: what you did isn't illegal by any means, and in some circumstances, it's probably exactly what you want.
