Now how to paste variables. If you have a big variable, let's say with the content of a file, and you need to paste it to a sub. Paste the reference, or you will use more memory duplicating the varialbe inside the loop

Another approach is using variable aliasing to @_ array in subroutine calls:

$data = 'foo' x (1024*1024) ;
test($data) ;

sub test {
  if ( $_[0] =~ /foo/s ) { print "bar\n" ;}
};

This is memory efficient too.
