Hello, I have a question that I'd like to know why isn't possible do what I pretend to do. It's reading a variable from an array to use in an expression.

Example: 

my @array = ('A1', 'A2', 'A3', $1, '$2');

my $message = 'If you choose a yellow car everyone will follow you!';
my $my_trigger = 'If you (.*) a (.*) car (.*) will follow you!';

if ($message =~ m/$my_trigger/g) {

	my $var1 = \$array[3];
	
	my $option = \${$var1};
	my $color = $2;
	my $whom = $3;
	
	print "option: " . $option;
	print "\ncolor: " . $color;
	print "\nwhom: " . $whom;
}

Why can I use inside the if $1, $2, $3 ... but can't use reading that value from an array. The question might not make sense for lot of people, but I am curious why doesn't work... only return to me as a string and not a variable. It's possible to return as a variable?
