There is no String#compare equivalent for Char, right?

Following is a example.

'A'.compare('a', case_insensitive: true)

You can do:

'A'.downcase <=> 'a'.downcase

The reason why case insensitive comparison exists for String is because otherwise if you call downcase on it we need to create a new string and memory, and that’s not efficient.

But when calling downcase on a char there’s never a need to allocate memory.

So I don’t think there’s a need to add case insensitive comparison to Char.
