Technically it's a struct literal. It's only a constructor if you 
define one, in which case struct literals no longer work. E.g.,

struct Foo {
     int x;

     this(int a, int b) { x = a + b; }
}

Without the constructor, the literal Foo(10) would be valid, but 
with the constructor you'll get a compiler error.
