Re: Lexical::Alias & subroutines

Just curious, but why is the following so ugly that you would resort to making some kind of alias?

sub foo
{
    my $byRef = shift;
    ...
}

Shifting makes $byRef a copy of the variable passed to the sub. Jenda indicated he wants to modify the argument passed to the sub so he needs an alias. $_[0] is an alias but he'd like to work with it using a more friendly name.
