How about showing a Warning when trying to create a large namedtuple?
The Warning contains a reference to a bug issue, and should describe
that if they really, really need to have this limitation removed, then
they should ask in the bug report. Just so that we don't complicate the
code unnecessarily without a real usage.
In Python, classes are largely syntax sugar for a dictionary anyway, if
they needed such a large namedtuple, they should probably reconsider
using dictionary or list or real classes instead.
