Unlike some languages, Python requires that the "self" parameter be
explicitly named everywhere, including in the method arguments. Thus
one would have to write
cdef class a_class:
cdef opaque_pointer* the_handle
def __init__(self, table_name):
self.the_handle = init(table_name)

I hope Cython works for you. If you don't know Python yet it will
probably be a bit of a steeper learning curve than otherwise, but
sure beats writing everything by hand.
