At the time PEP 227 was written, nested scopes were contentious. (I recall one developer who said he'd be embarassed to tell his co-workers he worked on Python if it had this feature :-). Rebinding was more contentious, so the feature was left out. I don't think any particular syntax or spelling for rebinding was favored more or less. > On this particular idea, I tend to think it's too obscure > as well.
