I think its easier to explain - it will actually result in a constructor
on the prototype.
The actual constructor function and the .constructor property really
should always be in sync - this helps with that.
So the proposal is that the class body declares a function called
"constructor" in with other functions that will end up on the
[[Prototype]] but the instance created from 'new' operating on the
class function call will have an own property "constructor" that
points to this function. Will the property also appear on the
[[Prototype]] under 'constructor'?
No, it is same as existing reality. Do not read "the .constructor
property" from above as "own .constructor property" (which may have led
to your conclusion) but as "shared-via-prototype .constructor property",
which is exactly the current status quo.
That's the beauty of 'constructor' named prototype/instance method - the
status quo is such that it already is there, though it is created nehind
the scenes as the magic of making a function also a constructor. So by
using it nothing new is added.
