[Python-3000] Reminder: Py3k PEPs due by April

[Raymond Hettinger]

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.
Replace:
   'hello         ' \
   'world         '
With:
   ('hello        ' +
    'world        ')
