Er, from my reading that's clearly not what the Wiki says for
WeakMap. And it also is not what V8 implements, for either
WeakMap or Map.
Sorry, I was relying on Rick's testimony that the answers were 1)
yes, 2) no.
Yes, when I first considered the topic, it seemed to make some kind of
sense (based on a desire for consistency), but I also don't believe
that should be the case now—I even noted that I had always
subjectively viewed resulting behaviours as "strange".
Oops, then I really misread one of your messages -- I thought you had
tested in V8.
I'm not sure I've ever encountered code in the wild that made any
intentional use of built-ins Foo.prototype-as-firstborn - can anyone
on the list point to some compelling use cases?
If it doesn't matter, we could make all the built-ins'
constructor.prototype objects be instances of Object (except for the
Error subclasses!).
That would be nice. Then we'd have
class C extends B {}
assert(C.prototype instanceof B)
and per Allen's nifty trick of avoiding class-side inheritance from
Object (which made Dave hear angels sing):
class C {}
assert(C.prototype instanceof Object)
