Yes, it makes parsing (especially of member templates) hard:

 template(int N)
 struct X {
    template(int M)
    X(M) f();
 }

 void g() {
    X(100) *x; // Multiplication or definition?
    x->f(3)(); // You'll still want the `->template' hack
 }

The use of braces seems very viable though. Apparently, this
had been proposed to the committee by a member with an extremely
strong reputation in programming language grammars and parsers.
I am surprised (and disappointed) that his advice was not
followed.
