[Python-Dev] PEP 236: an alternative to the __future__ syntax

[Guido van Rossum]

> Argh. It's now at http://www.informatik.hu-berlin.de/~loewis/python/directive.diff
> 
> > other tools that parse Python will have to be adapted.
> 
> Yes, that's indeed a problem. Initially, that syntax will be used only
> to denote modules that use nested scopes, so those tools would have
> time to adjust.
> 
> > The __future__ hack doesn't need that.
> 
> If it is *just* parsing, then yes. If it does any further analysis
> (e.g. "find definition (of a variable)" aka "find assignments to"), or
> if they inspect code objects, these tools again need to be adopted.

This is just too late for the first beta.  But we'll consider it for
beta 2!
