Function Syntax
Returns the number of keys in the specified aggregate.
Code Samples
This example function uses count to create a new key in a map (defined outside the function to hopefully eliminate some confusion).
item [int] my_map;
boolean newkey(item i) {
map[count(map)] = i;
}

Special
This function returns 0 for an empty map (i.e. with 0 keys).
