What annoys you

What annoys you the most to see in someones code?
What annoys you the msot in a programming language?
Mention all the programming related annoyances.

to name a function pointer I would use shitCase; this reminds me of the fact that it's not a hardcoded function, but it's something that is modified during runtime.
I don't think this difference is big enough to deserve a different naming convention, but it's a matter of style.

I make a visible difference between these things for the same reason you format ANYTHING in your code. Why do you use whitespace? The computer doesn't care how your code is formatted... but you do. It helps you debug and maintain your code.
Good point, but it's a matter of style. If you prefer so much differentiation, why not use Hungarian notation?

Even if your language allows you to do exotic things like change hardcoded classes or functions at runtime, you still should make a distinction between those you will change at runtime and those you won't.
Why? I'm not saying I shouldn't, just asking why. I never thought objects being created at run-time are so different from objects created at write-time. Think of it as the difference between i = 2 and i = 1 + 1.

The reason for this ambiguity is just because you use lower_case. lower_case and camelCase are mutually exclusive because of the ambiguity with single words.
I use lower_case, CamelCase and UPPER_CASE, which are perfectly compatible (since I don't declare UPPER_CASE constants only one character long).

lower_case fucking SUCKS. It's hard to type, hard to read, and generally makes code look shit ugly.
I think exactly that of shitCase, not lower_case.

Also, if you're annoyed by underscores, edit your keyboard layout to add them to an unshifted key. Or use Lisp; you can use just a minus sign in lisp.
