Dynamic associative array, to hold many values per key

[Logesh Pillay]

I want an associative array in d programming language. The key is 
a struct with two shorts. Easy so far.

struct kie { short a; short b; }
short[kie] possibles;

Problem is I want to hold more than value per key. Dynamic would 
be useful so it can grow and shrink per key When I try to 
allocate a dynamic array as value to a to key i.e

short[] temp; ... possibles[k] = temp;

I get the understandable error.  Error: cannot append type 
short[] to type short

How do I declare an associative array where the values can be a 
dynamic array of numbers?
