I've tried adding a new class Constant in function.py:

class Constant(ffc.Constant, dolfin.cpp_Function):

    def __init__(self, domain, value):
        "Create constant-valued function."
        print domain
        print value
        #ffc.Constant.__init__(self, domain)
        #dolfin.cpp_Constant.__init__(self, value)

But I get the following error message:

  File
  "/scratch/fenics/dolfin/dolfin-dev/local/lib/python2.5/site-packages/dolfin/function.py", line 411, in <module>
    class Constant(ffc.Constant, dolfin.cpp_Function):
TypeError: Error when calling the metaclass bases
    function() argument 1 must be code, not str

How is this possible? There should be no metaclasses involved here
(except the built-in Python metaclass type that is always there).
