Hello dear Monks ) Here's some code: 
my $r = 300;
my $g = 'g' . $r;
print "$g\n"; #would be 'g300', that's ok
$r = 500;
print "$g\n"; #would be 'g300', but wanted 'g500'

So, is there a way to make $g change as $r changes? Thanks in advance.

In reply to if $a = 'some' . $b, and $b then changes, how to make $a change too? See inside. by Doctrin
