Certainly better to repeat in List domain. Logically, how would the
category know about the actual representation of List. Furthermore,
there might be other domains
I think in this case Spad compiler can't do much about it:
It generates a SPADCALL in general cases for "rest", and
generates an inlined "CDR" for List.
So the repeat of defination is unavoidable. (See the arrays,
there's map! in OneDimensionalArrayAggregate, but those
array domains repeat the
