Is there a reason why we need to restrict the argArray to apply

Please define "array like" and give examples (possibly including
DOM
nodelists, which thanks to "live update" are are neither lists nor
arrays, rather more like cursors).
"array-like" means having 'length' and array index properties.
And the constraint that index < length for all index properties?
No.
And other constraints from ES1-3 [section 15.4] as follows?
No.
If I'd meant to include those constraints, I would have said so.
Bully for you. What I'm looking for is your rationale.
The constraints are not needed here. You just read 'length' using
[[Get]], and then read each array index property from 0 to
ToUint32(length)-1 inclusive using [[Get]]. This is how all of the
generic methods that operate on array-like objects work.
Good, this is the rationale I sought.
I think you're making mountains out of molehills in this subthread;
a Function.prototype.apply that treats its arguments array generically
is quite easy to specify (and implement).
I agree, and I've made no mountain. You must be thinking of some other
"subthread". If asking you for rationale makes a mountain, then climb
it.
