Thanks much. It was confusing because the code says certain classes inherit Implicit, but epydoc shows the class Acquirer.
Other than understanding how Python wraps C classes -- is there anyway of seeing where the classes are defined, understanding the methods + method definitions, in a Python-looking way?
