Hi Bob,
Well, I tried it, and a few permutations thereof, and the only real difference I see
with our is that the our makes the inner declaration a comment. Without the
declaration of a local [not Perl local, just local] variable in the block, the block
would have full access to the variable, anyway.
This has certainly been most instructive. It also makes me very leery about declaring
anyvariables outside of function definitions. I just don't see any real porotection
coming from the my keyword alone.
Joseph
