Before we add functions that differ only in details, let's consider
the APL approach to this kind of problem: concatenate the two arrays,
sort the result, and split them again. How efficient would that
be in Python? It mostly depends on the concatenation (which APL
implementations treat with special care because it is extremely
frequently used).
