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!

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
