Christoph Reiter added the comment:
Why not just do the following:
>>> from collections import namedtuple
>>> Point = namedtuple('Point', ['x', 'y'])
>>> Point._source
"from collections import namedtuple\nPoint = namedtuple('Point', ['x', 'y'])\n"
>>>
The docs make it seems as if the primary use case of the _source attribute is
to serialize the definition. Returning a source which produces a class with
different performance/memory characteristics goes against that.
