I seriously doubt that.

If you look at sub get in Mechanize.pm: 

sub get {
    my $self = shift;
    my $uri = shift;
...

The parameter $uri is passed by value, which means it is copied.

Even it is modified later on, you'll never see that in your script because it's just a copy that's modified.

However the uninitialized value might be a hint. Check $url for definedness, and die if it's not, then rerun your script.
