Why not use a module global? It isn't hidden, but it is quite a clean
approach. Modifying your example...
spam_count = 0
def spam():
global spam_count
spam_count += 1
return "spam " * spam_count

I wouldn't be too worried about that. Although namespaces can become
somewhat crowded with all these extra names, there can be benefits in
exposing such names, too, but if you find this too annoying, it could
be advisable to collect these entries and put them in another
namespace, maybe a class or a module.
