It should be Literal, not PrimaryExpression. There is no technical
difference (since Literal is only used as one of the alternatives
for PrimaryExpression), but it's just common sense that a
RegularExpressionLiteral is a literal.
Agreed, presumably Allen agrees too. It's obvious now that you point
it out ;-).
Homefully I'm relatively agreeable...Strictly speaking
RegularExpressionLiteral is now semantically more like an
ArrayLiteral or an Object literal
Those are still called Array Initialiser and Object Iniitialiser,
right? Not to belabor the point, but they aren't literals in the same
sense, although Object Initialiser's property names are literals
(constants). These are expression forms with evaluated terms inside
the bracing.
in that one of them evaluates to a different object each time it is
executed.
That's true, but it doesn't make a literal what it is, in the
grammatical sense.
However, I don't think it actually makes much of a difference
whether it is a Literal or a PrimaryExpression and since I'm
certainly not proposing that we move it from section 7 to section 11
at this point in time it probably makes more sense to say it is a
Literal.
Cool. That does seem like the minimal change, and it seems worthwhile
also to keep Literal meaning "lexeme".
