Language change: All functions and methods declared lexically outside any class are now

automatically static, and fields are no longer allowed to be declared there.  Stated
differently, all heap state must now be declared inside an explicitly declared class,
and functions and methods declared outside any class can be viewed as belonging to
the module.  The motivating benefit of this change is to no longer need the 'static'
keyword when declaring a module of functions and methods.
