If a browser does not support Object.freeze, seal or
preventExtensions, it likely does not support fixing proxies either.
Calling the fix() trap explicitly via Proxy.trap would still not

No.
Inheritance-based instanceof testing for the purpose of dynamic

At first glance this would mean for me: rename drawShape to draw. draw

Weak Maps seems to have superseded ephemeron tables.
They are non-enumerable, does this also exclude any call that gives you
an array of the current keys?
If this is the case then it excludes the primary use case we have in
node for ephemeron tables.
I can understand why you might want to
Why would you want to enumerate the keys in a weak map?

Don't you generally need to manage the policy for these kinds of requests
manually anyway? In particular, you can't actually tell if a user has abandoned
their session, since the browser doesn't let you know when that's happened. So
Hi Mikeal,
I do not yet understand your server example. Perhaps a bit of illustrative
code would help?
In any case, within memory-safe gc languages, there are several well
motivated enhancements of the API of the collector. Several of these are
fundamental, in that there is no way to emulate

Given this, is there any reason for anything but import ModuleName.* then?
