Sorry, but I don't get it. Can you elaborate, please?

This is the array in question: 
https://github.com/rumbu13/decimal/blob/master/src/decimal/integrals.d#L2072

First time, I tried to use mixins to generate the array, in order 
to avoid writing the same thing again and again. The mixin 
solution was nice until the compiler served me a nice Out of 
Memory error, that's why I finally used a hand-written array.
