new A().b() currently requires extra brackets/parentheses

Maybe you could use a template:

auto create(T, Args...)(Args args)
{
     return new T(args);
}

class A
{
     int i;
     this(int i){this.i = i;}
}

import std.stdio;

void main()
{
     create!A(5).i.writeln();
}

But I agree with you it would be nice if dmd supported 'new A().b()'.
