[phobos] static opCall for construction

[Denis]

IIRC, there is currently no way to have default ctor with non-default
behavior, but it's possible to achieve with static opCall. E.g.

struct Foo
{
    this() { writeln("ctor"); } // disallowed
    static Foo opCall() { writeln("static opCall"); return Foo(); } // allowed
}
