Hmm this works, so I guess the bug should be renamed, but I'm not really sure what is going on: 

module testaa;

import tango.io.Stdout;

void main(char[][] args)
{
	//From first example @ http://digitalmars.com/d/1.0/arrays.html#associative.
	int[char[]] b;
	b["hello"] = 3;
	auto val = b["hello"]; //Line 10.
	Stdout(val)();
}

  • status changed from new to closed.
  • resolution set to invalid.

This is a DMDFE problem, please file it in the DMD bugzilla.

Reduced example: 

struct Stdout {
  static Stdout opCall(int i = 0) { Stdout s; return s; }
}

void main() {
  int[char[]] b;

  Stdout(b["hello"])(); // error, DMDFE thinks you want to declare b
                        // of type Stdout["hello"]

  int (funcptr[4])(); // declares int[4] funcptr;
}
