Following up on a python-3000 discussion about making porting from 2.6 to 3.0 easier. Martin suggested making this its own thread.
This proposal is to add "from __future__ import unicode_string_literals", which would make all string literals in the importing module into unicode objects in 2.6. This is similar to the -U flag, but would only affect a single module at a time. I think history has shown that -U isn't really usable when using any number of modules, including many in the standard library. There was another proposal from Christian Heimes to add "from __future__ import py3k_literals", which would: 1) '' creates an unicode object instead of a str object 2) b'' creates a str object (aka bytes in Python 3.0) 3) 1 creates a long instead of an int 4) 1L and u'' are invalid 2) is already taken care of in 2.6, since: type(b'') == str. I don't think 3) is necessary. It's an implementation detail. 4) is really two issues. It's my understanding that there's a 2to3 fixer for both of these issues. But I'm open to debate on this. I'm willing to implement this if there's consensus on it.
