I noticed that some functions (in or not in the ABI I don't recall right now,
I'm not at my desk) need the topology parameter only because the topology
structure holds pointers to platform-specific routines. That seems like a
confusing generalization of the parameter's meaning/purpose.
It would be helpful, when creating bindings for object-oriented languages, if
for instance operations on bindings could be methods of the bindings object,
without the complication of holding the topology pointer in each object instance.
