I invite you to describe your _better_ coding style under aproximately following
restriction.

You have to code a script used by a generator that offers you three definition
facilities: PRE, POST and ITEM and you must implement a sparsely populated
function f from natural numbers to natural numbers. Where sparsely means at most
10,000,000 elements out of 4,000,000,000 possible elements and the values of the
pairs for the function are given as $(x) and $(y)

My _bad_ style looks like this:

<script>
PRE:
define uint X;
define uint Y;
Y[X] f;
void init( uint x, uint y){
f[cast(X)x]=cast(Y)y;
}
static this(){
POST:
}
ITEM:
init($(x)u,$(y)u); 
</script>

That are nine lines to understand and maintain.

In case you will accept this invitation in addition to your coding solution I
expect a sound argument, why your proposed _better_ coding style will spare a
significant amount of maintenance man time.

Otherwise it should be clear who of us is a warrior.
