That makes sense! There is one other case where I think that work is hugely relevant to Rust, though: The growing number of cases where a global need must be satisfied at-most-once. More and more cases of this have been cropping up:
- Global allocators
-
stdplatform backends - Linking to external libraries statically
- Panic runtimes
- Replacing crates behind the facade
- 1-of-N cargo features (for selecting backends)
- lang items
- event loops
- etc
