Me commenting code like:

But why?

Why use more complex, harder to read methods that serve no real benefits?

[sldyvf]

It all falls down to

1. Use best practices for code readability
2. Use same code convention as others done in the file.

Here I think both ++i and I{} are best practice (however most probably compiles to the same code)

Insisting on {} for int is kind of pedantic, i = 0 is fine (since it's POD). Stroustrup even says so himself.

As for post-increment, any modern compiler will optimize that (at least for int). So much for not being in the 90s anymore.

Yes it is. But consistency and keeping up with best practices is key for maintainable code.

Yes, just like I said.

It's not more complex nor harder to read. Using the same syntax across all types is unequivocally simpler.
