you got that backwards: GeneratorType was added in Python 2.2, but isinstance
has been around for a long time (1.5 or so).

without looking at SimPy, it sounds like the best way would simply be to remove
the type test.  if the code uses generators in the usual way, it will simply fail on the
first __iter__ or next call if it's given the wrong kind of object...
