exposed in header files. Fixed a few comments in these headers. As we might have expected, writing down invariants systematically exposed a (minor) bug. In this case, function objects have a writeable func_code attribute, which could be set to code objects with the wrong number of free variables. Calling the resulting function segfaulted the interpreter. Added a corresponding test.
