Michael Cuthbert added the comment:
Here's a rather obscure bug that I was able to catch before we put this into
action: doctests inside the __doc__ for namedtuples (and perhaps all
namedtuples?) are instances of property, have .fget, but do not have
.fget.__code__. Thus one more check is needed:
if (lineno is None and
isinstance(obj, property) and
obj.fget is not None and
hasattr(obj.fget, '__code__')):
obj = obj.fget.__code__
lineno = getattr(obj, 'co_firstlineno', None)
