Python 3's promise was "we'll break all of your code in exchange for a few minor things some people think are improvements." When users balked, the devs decided to force the change by brow-beating and shaming users, with predictable results. Perl 6 had lots of carrots, but was so different that the only plausible portability story was to run existing code in an embedded Perl 5 interpreter with some kind of interoperability layer. It's a new language, still looking for its niche. Ruby devs were so used to breaking changes that they considered porting to 1.9 to be more of the usual. Meanwhile, C and C++ happily coexist, despite major divergence by C++ and minor incompatible changes by both languages.
