Improved Function.prototype.toString in ES6?

# Nicholas C. Zakas (13 years ago)

I noticed that there is a proposal to improve how Function.prototype.toString works in ES6: harmony:function_to_string

However, there doesn't seem to be any update in the existing ES6 draft, as it says:

15.3.4.2 Function.prototype.toString ( )

An implementation-dependent representation of the function is
returned. This representation has the syntax of a
FunctionDeclaration. Note in particular that the use and placement
of white space, line terminators, and semicolons within the
representation String is implementation-dependent.

The toString function is not generic; it throws a TypeError
exception if its this value is not a Function object. Therefore, it
cannot be transferred to other kinds of objects for use as a method.

Are there going to be a changes to this in ES6?

Thanks, Nicholas

This is probably a good place to reference esdiscuss/2012-July/024260 in reply to your question.

Basically, these are incomplete working drafts. Much is not yet included in the drafts.
