But will structural pattern matching be back-ported, though?
Certainly an incompatibility, if not a breaking change per se.
- kdmccormick 4y agoGP means there are very few backwards-incompatible changes in new releases. There are plenty of forwards-incompatible ones, though.
- fnord123 4y agoHow is pattern matching a breaking change? If your code doesn't have it how would it break?
- nedbat 4y agoSome people might mistakenly assume that "match" and "case" are now hard keywords, which would of course break lots of code. But they are soft keywords, so there's no issue.
