I have a (perhaps stupid) question regarding the Array type syntax. What is
the use case for a type like:
[string, double, ...boolean]

homogeneous lists of variable size, but I don't really see when I would use
a hybrid like
'var' and 'const' need to be added to the lookahead set on
ExpressionStatement. That will take care of the ambiguity.

The grammar is ambiguous.
var [x, y] = expr;

statement.
How does the "length" property work for structural type literals? Is it always
a fixture?

Enclosed is the first draft of the description of array initializer
syntax, which has evolved quite a bit in ES4. The draft feels a little
raw, maybe because we have yet to pin down all aspects of how structural
array types interact with everything; please read critically and ask
difficult questio
