There seems to be a lot of controversy on how to properly check if
something should be callable. There isn't any way to determine that in

The internal IsCallable determines if an object has a [[Call]] property.

Will that be available as a language feature, not internal?

For example:-
  Object.isCallable( document.images );

- would provide a check to internal IsCallable and return the result.
