Among the huge and infinite number of fauceirs, software objects, though their number is rapidly growing, play only a negligible role (see set diagramm), but they are important to understand fauceirs as Mato recently explained by his amended fauceir definition.
The key abstraction that underlies fauceir definition the encompassment of information and control function is accomplished by software objects, and there are some other similarities, too, which include heritability.
Usually, software objects cannot evolve, this is because they are slaves and under tight control by their masters. That is their liberty value goes to zero. If they were allowed to have the tiniest degree of liberty, the whole computer would crash. As declared in an earlier post, the liberty to react imprecisely is a prerequisite for evolution to take place.
