You'll need to create a custom MIMEFILTERS filter for this.

Having a general purpose one would be too complex and riddled with
false positives.

I think the idea is nice, but such capabilities would have more
success on a per-list/archive basis.  For example, if the list
is known to be about Perl, with code examples being common, you
can register the "perl" filter for that archive, and that archive

(With Perl, you can just tell everyone to post messages in POD, and
 then just use a POD filter :-)

Another example is when another user recently posted about
auto-detecting python code.  However, python examples can conflict
with quoted-text rendering.  Therefore, something that would
highlight python code should only be applied to archives where
python code is common.

Side Comment: Now, if such code was tagged with its own media-type,
then something more general can be done.  I.e.  Messages are
authored using a multipart type, intermixing text/plain with
the code snippets.  For example:

  Subject: Perl code example
  Content-Type: multipart/mixed; boundary="XXX

  Content-Type: text/plain

  Check out the following code snippet:

  Content-Type: text/x-perl

  if ($x) {
    print "HELLO\n";
  } else {
    print "GOODBYE\n";

  Content-Type: text/plain

  Blah blah blah.


Of course, do not hold your breath for people actually doing this.
Most popular MUAs do not allow building such constructs easily,
if not at all.  It seems common practice nowadays for multipart
messages to be only for attachments versus a sequence of differing
(inline) media-types.
