The parameter passing of Python (positional parameters, default values,
named parameters, excess positionals, excess named) is extremely
flexible and allows methods to have a large number of parameters that
no-one ever cares about. The graphics packages use this a lot.
However, it is core to Python but not to Java and Groovy. I can see the
use case but not the way the original example was set out. There need
to be ordering rules.
