I think, too, that those lazy functions would be very useful, and I look
forward some way to express also placement new.
Ideally, I would like to delay which version of new is called to the call
site, so I would need a new2_ lazy function such that
'new2_<T>( _1 ) (x)' is still a functor with overloaded operator (), that
can be called with 0 arguments (normal new behaviour), and with 1 argument
(placement new), ...

Would it be generally useful to have a variant of "new_" that returns a

Yes, I think this will be very useful.
