      Learned today that Perl 6 won't be compatible with 5. Luckily I have no skin in the game, but it's amazing that language designers made this mistake after the hard lesson of Python 2 to 3 — a division that will have taken 12 years to resolve (if the 2020 sunset works this time).

      Well, perl6 also has been in the works for nearly 20 years. So it couldn't have learned from the python 3 disaster. But I think one can make some inference from the time it has taken do design perl 6, to how likely it'll gain wide adoption.

      Leaving aside the time it has taken so far, I'm not sure the situation is quite comparable: I think a lot of the python2->3 issue was that there was no meaningful selling point to go for 3, except largely pointless pain. The changes for perl6 are a lot larger.

      I get what you're saying, and the Perl 6 improvements do look good, but even so, you really do need to favor backwards compatibility in a language above almost all else. The rift will likely be ~irreconcilable. Perl had the benefit of hindsight where Python didn't.

      I don't understand what you mean with benefit of hindsight - perl6 started *way* before python3?

          It doesn’t matter when it started — it only matters when it was released. Any time up to and including that point you can change (go for backwards compatibility), or cancel your plans.
