One point to clarify is that the reason it bugs me, apart from wanting vars to only live within the scope where they are needed, is that I might re-use the name $vrx later, with possible side-effects.

If you use warnings, you'll get a warning if you redefine a new my $vrx in the same scope as the first. If it's not in the same scope, then it'll be a different $vrx, so there should be little to no chance of unintended side-effects.

Of course, the better way to deal with it would be to use a more meaningful/distinctive name so that it's unlikely that you'll have cause to re-use the name...
