I'm reading the Python extension tutorial, and I cannot believe the embedding section. It tells me the only way to call a python function is to callout to python to pass back a function object which I then save so I can call it when I need to. This seems ridiculous. Surely there is a way to obtain Python function objects without going through that! Does somebody have a way to ask for a function by name?</blockquote>
