I believe that use cases for rebinding globals (module attributes) from within a module are more numerous than rebinding in an enclosing lexical scope (although rebinding a name in the global scope from a local scope is really just a specific case of that). I would think this was probably a motivator for the 'global' key word to avoid clumsier workarounds. Since there were no nested lexical scopes back then, there was no need to have a construct for arbitrary enclosing scopes. -Almann -- Almann T.
