No, the _lexical grammar_ of ECMAScript (Ed. 5.1) says that `new' is a 
keyword (section 7.6.1.1), and that `+' is a punctuator (section 7.7).

The _syntactic grammar_ calls `new' and `+' operators, as in "11.2.2 The 
`new' Operator" and "11.6.1 The Addition operator (+)".

"Productions of the lexical and RegExp grammars are distinguished by having 
two colons “::” as separating punctuation. […]" (section 5.1.2, last 
paragraph).

Correct for "operands", in the syntactic grammar.  Operators do not have 
arguments; functions (and by extension to OOP, methods) have them.

Yes, we are.  `+' is an operator in the syntax of ECMAScript; it has 
operands.

I get it now: you are trolling again.

Wrong.
