Thanks for the invite.
I had asked Ben what he thought about allowing the following syntax as a
synonym for `new Foo()`:
Foo::new()
That would be backward compatible because you currently cannot have a method
named `new()`.

Yes, off list Ben said he did not see the need for it, so I did not bring it up
on the list.
But now since he has invited me to... :-)
If we had such syntax then that would also Andre and others to use (and reduce
the necessity of needing so many parens:
Foo::new()->bar()
Thoughts?
