    For my derived classes I am using the following "quick and dirty"
  approach for subs: I made calls to ex:subs() for components of the
  derived class, and then call a constructor with these substituted
  components.

  [Disclaimer: the above approach is likely fundamentally wrong and
  resulting from my poor understanding of C++ class inheritance.]
