How does this have anything to do with the 3.* transition?</div><div class="gmail_quote"><br></div><div class="gmail_quote">But plenty of us are kind of stuck on 2.7 at this point -- we can upgrade, but can't accommodate a major shift (for me it's currently wxPython that's the blocker -- that may be the only one. Others are either supported or small enough that we could handle the port ourselves.)</div><div class="gmail_quote"><br></div><div class="gmail_quote">But anyway, if you don't hate 2.6 back in the day, why hate it now?</div><div class="gmail_quote"><br></div><div class="gmail_quote">(yet, I know Donald didn't use the "hate" word). </div><div class="gmail_quote"><br></div><div class="gmail_quote">I guess my pint is that you either would much prefer to be working with the latest and greatest cool features or not -- but if you do the problem at this point isn't anything about py3, it's about the fact that many of us are required to support old versions, period.</div><div class="gmail_quote"><br></div><div class="gmail_quote">-Chris</div><div class="gmail_quote"><br></div><div class="gmail_quote"><br></div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"> However I can't really justify for most situations supporting _only_ those<br>
things because even today they are not the dominant version (or really close<br>
