Hello list,
I'm still fighting the syntax of JS2. Attempting to feed it into a
parser generator (menhir, for the moment), has already allowed me to
find a few typoes in the spec and a few useless variables in the
reference implementation, which is all I have to show for the moment.
That and the fact that all XML* productions seem absent from the RI.
At the moment, though, I'm being puzzled by rule 317:
ExpressionStatement
| ListExpression (allowColon, allowIn)
[if lookahead not in { "function", "let", "{" }]
Besides the fact that this rule is annoying to implement, does it
actually mean what it intends ? In addition to blocks, it also prevents
an assignment to an object pattern from starting the ListExpression. Is
that desired ?
Thanks,
David
P.S.:
I forgot where I found that version of the grammar, it's dated
14/10/2007, so I assume it's the latest. Where are they to be found, in
general ?
