Hello Monks, This is a question that touches quite heavily on computing theory, but that can also be tied to Perl, semantics, and "Just Plain Cool". I was wondering if there was any way to determine how similar sections of code are. For example: 
$x++;
$x = $x + 1;
$x += 1;

all do the same thing. Does there exist a way to identify functionally similar blocks of code, and if not, can anyone point me in the right direction on how to do this? Thanks in advance!
