happen is that the new code is still broken.)

  Cater to that.

  was no slouch before; now it screams.
+ Improve msg when giving up on a goofy future statement.

Otherwise printlist(surprise) will fail with a TypeError, because map
is called with an argument that doesn't support iteration.

The descr changes moved the dispatch for calling objects from
call_object() in ceval.c to PyObject_Call() in abstract.c.
call_object() and the many functions it used in ceval.c were no longer
used, but were not removed.

Rename meth_call() as PyCFunction_Call() so that it can be called by
the CALL_FUNCTION opcode in ceval.c.

Also, fix error message that referred to PyEval_EvalCodeEx() by its
old name eval_code2().  (I'll probably refer to it by its old name,
too.)

- Remove various 'global' directives and move some global definitions
  inside the test functions that use them -- we have nested scopes so
  the old hacks using globals are no longer needed.

XXX There are still some loose ends: repr(), str(), hash() and
comparisons don't inherit a default implementation from object.  This
must be resolved similarly to the way it's resolved for classic
instances.

into indented lines each of which probably fits on a typical screen line).

XXX This is not sufficient: if a dynamic class has no __repr__ method
(for instance), but later one is added, that doesn't add a tp_repr
slot, so repr() doesn't call the __repr__ method.  To make this work,
I'll have to add default implementations of several slots to 'object'.

XXX Also, dynamic types currently only inherit slots from their
dominant base.
