However, the crucial requirement is that it can correctly parse method (member function) bodies so that dependencies are correctly identified.

Assembly is (currently) beyond my ken, so I'm hoping someone can piece together an implementation in a higher level language. Ruby is ideal, but I can parse PHP, Python, C, Java, etc. ...
Hi, I'm looking for a way to reverse a generator object. I know how to reverse sequences: foo = imap(seq.__getitem__, xrange(len(seq)-1, -1, -1)) But is something similar possible with a generator as the input and a reversed generator as the output (len(seq) stays the same, so the value from the original sequence can be used)? ...

I have an urlConf whit the name 'ver_caja' who receives as argument the id of a caja object, and then call the generic object_detail. The queryset is correct: get all the caja objects correctly. In the template I have the call: {% ver_caja caja...
In my project I have a lot of Ajax methods, with external client-side scripts (I don't want to include JavaScript into templates!) and changing URLs is kind of pain for me because I need to change URLs in my Ajax calls manually.
