[Python-ideas] AMEND PEP-8 TO DISCOURAGE ALL CAPS

IMO it's good to have some sort of visual differentiation between constants
and normal values. A lot of camelCase-based style guides use a k prefix
(e.g. kMyValue), but Python doesn't use it (other than PascalCase for
classes). If there were to be an alternative to ALL_CAPS for constants, I
guess maybe it'd also be PascalCase?
That being said, Dart 2 has dropped ALL_CAPS constants from its style
guide, and although everyone's survived just fine, I do somewhat miss being
able to immediately be able to see where something is coming from solely
from the case.
Side note: it seems like ALL_CAPS kind of came from macros being using for
constants in C and persisted.
