Hi Nils,
Replying to [comment:35 nbruin]:
> Just to make sure that the CPU cache effect is real, I tried a little
example
Thank you for your clear explanation! I am currently testing some
variations of my patch: Both for parents and for elements, one may or may
not have `__cached_methods` - if one has, then it can always inherit
cached methods from the category framework. And if one has the attribute,
then one may or may not search it in the `__getattr__` method - if one
does then the speed penalty for missing attribute assignment is reduced.
I can already confirm that the timings are affected by the presence of the
attribute. But I first need to finish my tests.
