The nice thing about being able to run others people code with your style is that your entire codebase stays in one consistent style. You don't run into issues like in other languages where one library author has done some dubious style choices which then propagates into your code. This was always a pain-point for me in Python.

And I'm not certain what scenarios you envisage where this would be an issue, why do you care how other people call your functions?

Dubious decisions in third-party libraries are common, but camel vs. snake case is probably not the main...

I care about how a function is called because so much tooling around programming is effectively grep. I can grep for a function name and get a pretty good idea where it is called. There's also a million variants of grep - git grep, unholy regular expressions (recently I used one to find all instances where foo is called with exactly 2, not 3 params, in Python), IDE plugins and so on. GitHub search? Google search for exceptions?

IIRC Nim comes with some kind of "nim-grep" that is camel-vs-snake-aware, but that doesn't fix all the other tools.

The minor gripe, additionally, is that you often have quasi-singleton classes called "FooManager", then a single instance called "foo_manager". Now... are these colliding? Or not, because the first letter _is_ case-sensitive? What does "fooManager" map to then?

In my utility function, this feature gives me nothing but concerns. But then again, I'm not (yet?) a user the Nim community provides for so... <meh>

Like this:

    type FooManager = object
    var foo_manager: FooManager

> Now... are these colliding? Or not, because the first letter _is_ case-sensitive?

Well as you correctly reason, the first letter's case distinguishes them.

Convention in the language is for types to start with a capital letter and instances start with a lower case letter.

> What does "fooManager" map to then?

It maps to the `foo_manager` instance because underscores are ignored, they're just for you. By the way, underscores are exceedingly rarely used in Nim code because they're not semantically significant, why bother.

Still, if you like you can use them in your code, and others can choose not to as they want. Clashing identifiers are a compile error so no worries.
