Constants

[ljharb]

"ugly" is very subjective. I don't find SCREAMING_SNAKE_CASE ugly at all, and personally, I love seeing it all over the place because it conveys immutability - for both global and all local constants. (Note that a local immutable variable isn't a "constant", and thus would use snake_case)

Do you have data beyond your own experience that suggests that "people tend to only use it when they feel obligated to"? I've never encountered that motivation before, personally.

In addition, if your syntax highlighting doesn't work well with any given capitalization, that's a problem with your editor, and shouldn't inform a style guide - most editors don't have any issue with it.

Thank you for the suggestion. We're trying to keep this style guide largely consistent with idiomatic Ruby, and I've never seen Camel_Case_ (or uppercase first letter for any local, regardless of what comes after it) in all the Ruby projects I've worked on so I think it strays too far from the norm.

I also disagree with the contention that local mutable state is a source of future bugs, but even if I come to agree with it, the deviation from idiomatic is still too much.
