Subject: question: referencing a variable with a variable

I come from a perl background.  I have gotten in the habit of using
references to variables instead of specifically calling said variable/
class/whatever.

Basically, I am wondering how I would translate the following into
ruby.

example 1:
sub my_sub
  {
  $choice = shift;
  $choices="this|that|foo|bar";
  if ( $choice =~ m/($choices)/ ) {&$choice}
  else {die "some witty msg"}
  }

example 2:

$this = 'var_name';
$var_name = 'i want this to print';
print $$var_name . "\n";

thanks
