And code is text, therefore it makes sense.

Consider that both <pre> and class="python" provide additional semantics to
<code>.
Typical source code *is* white-space sensitive, and thus when providing a
block of source code it makes sense to use the <pre><code> XHTML compound.
Now, in *addition*, there is nothing wrong with extending that with a
semantic class name on the <code> to indicate the language. For example,
many CSS specifications already do this with <code class="css"> and <code
class="html">.
But that's just proper use of semantic class names. It's ok to stop with
that. It's not even clear that it is necessary if you're thinking from the
perspective of a search engine which is going to go out there and index all
blocks of code -- it could just index instances of the <pre><code> compound,
and perhaps use other heuristics to determine the language of the code.
However, the real question is:
Is there really a need for a microformat for code?
I'm not convinced of that yet.
If you think there is, then I invite you to follow the steps indicated in
the process:
http://microformats.org/wiki/process
which will help scientifically answer that question based on microformat
principles.
Thanks,
