I didn't say that it was the same, I'm saying that you can get what you need through one of two routes: explicit semantics defined in the spec or something implementation-defined that takes advantage of the very broad definition of an identifier.

Encoding the "=" within the identifier effectively gets defining the semantics out of the specification and into the implementation, where you can implement whatever you want.
