Sorry for my late answer...
I still have some problems with english, so i hope i have got the most from your answer.
I think my last answer to austincheney, on JSMentors group, explains the goals of the function. i am saying that because i see you are there too.
I wrote about what i see as improvements for the syntax provided by the function Class and my point of view about OOP in Js, using constructors; i see my work as an achievement for the target goals.
What i just wrote is for these your lines:

I would like to encourage the OOP in Js, by my function, but using the native way provided by Js...
If you think i should, i can paste here my answer from the JSMentor group to share it with who could be insterested here.

Thank you,
Luca
