Generally, I like the idea of being able to switch from new Foo() to
Foo.new().
I have a question about your SIP. It seems that you propose that, when
the compiler encounters new Foo(x, y), if and only if c'tor signature
Foo(x, y) is not defined does it look for factory method Foo.new(x, y).
Presumably you considered the alterative that it looks for Foo.new(x, y)
first, then if not found, new Foo(x, y)? This would allow overriding
c'tors with a factory without removing the affected c'tor. Why do you
prefer the former option?
