The thing is that a capability is a pretty abstract notion. You can 
implement them as classes or as lambdas - I initially did them as 
classes, but decided that lambdas were neater, at least in the context 
of Python. I could be wrong. It could just be my particular bias, which 
is why I'd prefer, ideally, to be able to do either.

I'm sure if people want to be definition lawyers they can find 
documentation explaining why either of those isn't quite right, but I'm 
interested in functionality and the functionality is available either way.

Cheers,

Ben.
