* Proper handling for numeric conversion overflows * Moved internal converter names out of the way to prepare for user conversions * Added comments * Fixed a bug where None could be converted to the NULL target of a member function call, causing a crash. * Wiped out and restarted todo.txt * long long support * Added more regression tests and checks for current limitations [SVN r14094]

a quick regression test for a bug where None could be converted
|
|
to the target of any member function. To see it, we need to
|
|
access the __dict__ directly, to bypass the type check supplied
|
|
by the Method property which wraps the method when accessed as an
|
|
attribute.
