The toolkit implements an object model but presents it though a non-OO API. Daylight must do their own:

The run-time tests are needed to prevent:

  dt_getrole(reaction, mol);  /* parameters swapped */
Compare that to a more OO approach:
  mol.getrole(reaction)   # fails: molecules don't have
                          #    a "getrole" method

  reaction.getrole(obj)   # while a reaction does
Using a more modern language gives us those capabilities "for free" because they are built into the language.
