[Python-Dev] PEP 611 -- why limit coroutines and classes?

I want to question two specific limits. (a) Limiting the number of classes, in order to potentially save space in object headers, sounds like a big C API change, and I think it's better to lift this idea out of PEP 611 and debate the and cons separately. (b) Why limit coroutines? It's just another Python object and has no operating resources associated with it. Perhaps your definition of coroutine is different, and you are thinking of OS threads? -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-c...>
