This is now accepted and on its way to TC52! 🚢

Isn't an implementation required before a DEP is accepted?

In this case, the summary basically fully describes the semantics. In general, I think we should soften the language around how "necessary" an implementation is.

I agree that the semantics are clear, but it's nice to be able to concretely use a feature before sending it off to TC52. For this one in particular it's so similar to features in other languages that's less necessary, but in general it seems like a good step.

I agree. We're still shaking out the process but I also feel the first few DEPs went through very quickly. Hopefully over time we'll get to a mode where we spend more time battle-testing a proposal before it gets locked into the spec.

From my understanding, the original DEP proposal is now out of date. If anyone is here looking for the definitive specification, check out https://codereview.chromium.org//1031323002

The 3rd edition of the Dart language specification now includes null-aware operators. Check it out here: https://www.dartlang.org/docs/spec/
