An important step for RFC implementation is for people to experiment with the
implementation and give feedback, especially before stabilization. The following
RFCs would benefit from user testing before moving forward:
- No calls for testing were issued this week.
- No calls for testing were issued this week.
- No calls for testing were issued this week.
If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing
label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature
need testing.

refactorings that are necessary for further development and modification of the compiler.

error: hypothenuse can be computed more accurately:
--> src/main.rs:835:5

835 | (width * width + height * height).sqrt() / diag
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: consider using `width.hypot(height)`
