Polyfilled builtin functions shouldn't be constructors #188

Open cpcallen opened 6 years ago

cpcallen commented 6 years ago

At the moment, polyfilled builtins like Array.prototype.join:

are constructible, and
have a (writable, but non-configurable) .prototype property.

Neither of these should be true.

Maybe the solution is to provide an alternate Function constructor that does not create .prototype, and makes the function non-constructible.
