It should be able to modify it or not, without that affecting the function signature the caller sees. Whether the parameter is const or not is an internal detail to the function, not part of the interface.

True. I'm not really arguing with that.

But that's the fundamental reason it's not part of the signature!

It's just that the outcome of this reasoning appears unexpected for newcomers.

If the language changed every time a newcomer finds something unexpected the standard would be revised daily.
