Thanks for the reminder. I expect to write two:
* PEP to eliminate __del__ in favor of weakref idioms
* PEP on simpler alternative to abstract-base-classes
suggesting an occasional method special attribute
(so for instance a __getitem__ method can tell you
whether it thinks it is a sequence or mapping).
Here's that I think might not need a PEP:
* Eliminate implicit string concatenation: "abc" "def"
in favor of an explicit + operation. That simplifies
the grammar just a bit and the compiler already is
smart enough to do constant fold this operation at
compile time. When there are multi-line concats, I think
the parenthesis serves us much better than a trailing \
which is ugly and relies on having no trailing whitespace.
