This is the same behaviour as if you have
use vars qw($x);
$x = 2;
my $x = 5;
print $x
in one file. My variables, where visible, take precedence over package
variables. (Note that you can still get at the package variable with $::x or
$main::x -- it's not completely gone, nor is its value clobbered. It's only
invisible through the name $x until the end of the current block of file.)
Cheers,

If you're not part of the solution, you're part of the precipitate.
