Can you mention 3 cases of breakage the language has had in the last, let's say, 5 years? I've had colleagues in different companies responsible for updating company-wide language toolchains tell me that in their experience updating Rust was the easiest of their bunch.
> edition migrations
One can write Rust 2015 code today and have access to pretty much every feature from the latest version. Upgrading editions (at your leisure) can be done most of the time just by using rustfix, but even if done by hand, the idea that they are onerous is overstating their effect.
Last time I checked there were <100 checks in the entire compiler for edition gates, with many checks corresponding to the same feature. Adding support for new features that doesn't affect prior editions and by extension existing code (like adding async await keywords, or support for k# and r# tokens) is precisely the point of editions.

Could you elaborate on what you mean?
