No I didn't, I had no idea they existed, as I was depending on
http://gnuradio.org/doc/doxygen/page_pmt.html for information instead of
http://gnuradio.org/redmine/projects/gnuradio/wiki/TypePMT which has a
little more info on to_python().
My bad, I guess I wasn't thorough in reading about PMTs. I fixed my problem
now.
Thank you.
