Argument does not count because now we have 32-bits.

Argument counts, because you sometimes need to interface with other
programs/machines, and they have one more bit... This is the same with
Euphoria: EU integers ocasion some difficulties when interfacing C programs.

Do you have any "simple" solution for handling something as simple as an (A
and B and C) rule? (what people normally would regard as a rule)

Example case: Simplified rules for unemployments benefits. How to program
such rules?

To qualify for unemployment benefits....
1) you must be a national citizen (N)
2) you must be unemployed (U)
3) you must have earned more than $10000 previous year (I)
4) all facts must be documented
