[Python-il] @cached_property in Python 3.8 :-)

[Amit Aronovitch]

Well, this was actually merged to cpython master in August, so not really new by now, but I only discovered recently...

If anyone remembers our old snippets section in the wiki:
http://wiki.python.org.il/Code_Snippets_en#cprops:_Cached_properties_using_non-data_descriptors

And now (28 Aug 2018: exactly 9 years after that wiki post!):
https://github.com/python/cpython/pull/6982

No more having to choose between copy-pasting your own snippets or adding dependecies. It will be available in std functools
:-)

Very nice!

FYI I'm now a core developer of Python, and I'd be happy to help move forward other suggestions like this.
