If it's really a problem, we can also cache groups of test in one
cache, like
  is-math-stuff-cached
    eval cached-setting-of-all-math-stuff
  else
    foreach math-test a
      test-for-cached-answer-a-oh-it's-there-never-mind
      else
        ...
      end
      update-cached-setting-of-all-math-stuff
    endfor
  end


Ciao,
Michael.
