I'm -0 -- mostly because of the 3rd party doctests and perhaps also<br>
because I'd like 3.x to have some carrots. (I've heard from at least<br>
one author who is very happy with 3.x for the next edition of his<br>
"programming for beginners" book.)<br></blockquote><div><br>This reasoning definitely makes sense to me; with all the dependency-migration issues 3.x could definitely use some carrots. However, I don't think I agree with it, because this doesn't feel like a big new feature, just some behavior which has changed. The carrots I'm interested in as a user are new possibilties, like new standard library features, a better debugger/profiler, or everybody's favorate bugaboo, multicore parallelism. (Although, to be fair, the removal of old-style classes qualifies.)<br>
<br>I'd much rather have my doctests and float-repr'ing code break on 2.7 so I can deal with it as part of a minor-version upgrade than have it break on 3.x and have to deal with this at the same time as the unicode->str explosion. It feels like a backport of this behavior would make the 2->3 transition itself a little easier.<br>
