You could do it with anonymous subroutines. Just assume that every variable is a subroutine. It's not very pretty, though.

my %vars; # something to hold all your variables in

sub set_var {
    my ($name, $value) = @_;

    $vars{$name} = $value;
}

sub get_var {
    my $name = shift;
    my $var = $vars{$name};
    return ref $var eq 'CODE' ? $var->() : $var;
}

set_var(foo => "hello");
set_var(x => sub { return get_var('foo') . get_var('y') });
set_var(y => 'world');

print get_var('x'), "\n";
