Bug 20547 – Wrong error message when trying to "new" an associative array

DMD yields poor error messages when trying to allocate a dynamic array: void main() { int[int] a = new int[int]; // need size of rightmost array, not type int int[string] b = new int[string]; // cannot pass type string as a function argument int[string] c = new typeof(b); // new can only create structs, dynamic arrays or class objects, not int[string]'s } a and b should produce the same output as c.
