AA maker template
Here is a little template I wrote to create an AA given an array of keys and 
an array of values.  It's put in the public domain, so if you have a use for 
it, go ahead.  I'm relatively new to templates, so if I've missed something 
let me know; it seems to check out fine.
// Array maker template.
// Written by Ameer Armaly and placed in to the public domain.

class MakeAAException: Exception
 {
 this(char[] msg)
   {
   super(msg);
   }
 }
template makeAA(Tk, Tv)
 {
 // Tk is the key type, Tv is the value type
 Tv[Tk] makeAA(Tk[] keys, Tv[] values)
   {
   // There have to be the same number of keys as values.
   if(keys.length != values.length)
     throw new MakeAAException("The number of keys and values do not 
match.");
   else
     {
     Tv[Tk] AA;
     foreach(i, v; values)
       AA[keys[i]] = v;
     return AA;
     }
   }
 }
