Re: [Python-ideas] Modules as global namespaces rather than dicts

Another point, perhaps more difficult to address: Would for instance globals() then return a module instead of a dict/mapping?​

For compatibility, it would definitely have to return a dict. As a result, calling globals() would cause the "fast globals" flag to be cleared. My hope is that getting a reference to the module dict from user code is the exception rather than the norm. I.e. most modules would never have globals() called within their code. If it is too common, the flag will be cleared on most modules and we won't gain much speed.
