Jython is an implementation of the high-level, dynamic, object-oriented
language Python written in 100% Pure Java, and seamlessly integrated with
the Java platform. It thus allows you to run Python on any Java platform.
# test overloaded java methods dispatch logic in PyReflectedFunction
# needs to grow more tests. Uses javatests.JOverload as a bag of overloaded methods.
# (can be adapted to test alternative re-implemations even while they are developed
# write a *Envl class and change/add to to_test for that)
