Being in problem space is not always an advantage. Very often solution
space is magnitudes more stable and solid then continuously moving
problems. So "solution side" parts of problem-solution bridge became
more useful and reused.

The prime example of solution space thing is all sorts of
container/collections libraries, generic or common root ones. So the
lack of such standard libraries in Ada is a prooth of Ada's problem
orientiness. :))
