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. -- Ryan (ライアン) Yoko Shimomura, ryo (supercell/EGOIST), Hiroyuki Sawano >> everyone else https://refi64.com/ On Fri, Jan 4, 2019, 1:02 PM Abe Dillon <abedil...@gmail.com wrote: > I keep coming back to this great video <https://vimeo.com/74316116> about > coding style, and one point in particular rings true to me: > ALL_CAPS_IS_OBNOXIOUS > > It destroys the visual flow of code and for what?
