Re: if $a = 'some' . $b, and $b then changes, how to make $a change too? See inside.

It sounds you want code like this which uses references:

$ perl -Mstrict -Mwarnings -E '
    my $r = 300;
    my $r_ref = \$r;
    my $g = "g";
    say $g . $$r_ref;
    $r = 500;
    say $g . $$r_ref;
'
g300
g500

See perlreftut (a short tutorial) and perlref (the details).
