Basic Syntax Question

[WhatMeWorry]

I don't suppose there is a digital.D.beginner forum?

I've been staring at this definition for about an hour and I 
still can't decode it.

int[string][double[int[]]] a;  //
...
auto b = to!(short[wstring][string[double[]]])(a);  // this 
doesn't help either


int[string} a  // would be an Associate Array of integers with a 
string key?

int[]  // would be a dynamic array of integers,i believe?

But put the int[] inside of double[] and put that inside of [] 
and put that after the associative array, and my head can't stop 
for spinning.


If there is a better site or forum, please tell me and I won't 
waste people's time here. I did buy Andrei Alexandrescu's book 
and have it pretty well dog-eared. But i must be a pretty 
mediocre programmer.
