That shouldbe added (and I'm very curious why it isn't acceptable, it seems veryelegant to me).In fact, I'd like to see the PEP contain a bullet list of alternativeswith a discussion of why each is unacceptable or insufficient. The textas organized now is hard to follow for that purpose.Other comments:I disagree that "it is clear that 2to3 as a tool is insufficient" andthat *therefore* people are attempting to use unified source. I thinkthe truth is that people just prefer the unified source approach,because that is more Pythonic.I also strongly disagree with the statement that unicode_literals isdoing more harm that good. Many people are using it very successfully.In *certain contexts* (WSGI) it may be problematic, but that doesn'tmean it was a bad idea or that it shouldn't be used (given that aproject uses it consistently, as noted previously in this thread).As noted above, the native string type *is* available withunicode_literals, it is spelled "str('somestring').I don't understand the "Who Benefits?" section at all. For example, Ithink you'll agree I'm experienced working with email issues, and I don'tunderstand how this proposal would help at all in dealing with email.The PEP would be strengthened by providing specific examples of theclaims made in this section.I am -0 on this proposal. I will bow to the experience of those actuallytrying to port and support web code, which I am not doing myself.But I'd like to see the PEP improved so that the proposal is as strongas possible.--David
