Tonight I gave the presentation "The design of VLAM Compyle : A tower of languages from python to C++ using scheme" before MSLUG. A special thanks to Guillaume for inviting me.
For those who didn't show up (you should have, MSLUG is a fun group - plus, we were happy to have pythonistas join us from Montreal Python) all is not lost! You can get the slides. Also, I'll be happy to answer questions you might have.
