suggestion of implicit new

[shinichiro.h]

Hi all,

I guess D syntax can allow implicit new expression like following:

class C {
  this() {}
  this(int x) {}
}
void func() {
  C c = C();  // not new C()
  c = C(3);   // not new C(3)
}

I think the syntax is cute. And the syntax is not ambiguous and does
not make DMD slower. I have succeeded to implement the syntax into
GDC-0.18 (based on DMD-0.157). The following patch worked.

4076,4078c4076,4080
< //        fd = search_function(ad, Id::call);
< //        if (fd)
<           {
---

>               e = new NewExp(loc, NULL, e1->type, arguments);
>               return e->semantic(sc);
>           } else {

<               Expression *e = new DotIdExp(loc, e1, Id::call);

Any thought?
