Fellow monks,
In another one of my steps to learning Perl the right way, I'm trying to get my head around subroutines, namely passing data back and forth between. I did learn (by reading the Q&A) that data gets passed as a list, e.g., @_). But part of my problem seems to lie in what happens once in the subroutine. This works (right out of the Camel book): 
use strict;
use Data::Dumper;

my $name = "baggins";
&uppercase( $name );
print Dumper( $name );

sub uppercase {
    for (@_) { 
        tr/a-z/A-Z/;
    }
}

but this ones does not: 
use strict;
use Data::Dumper;

my $name = "baggins";
&uppercase( $name );
print Dumper( $name );

sub uppercase {
    for (@_) { 
        uc($_);
    }
}

Is it the $_ in the uc($_)? I'm sure it's insanely simple, but I'm not seeing it. Thanks!
