More to come, please file an issue if you have ideas!
The restriction category should, emphatically, not be enabled as a whole. The contained
lints may lint against perfectly reasonable code, may not have an alternative suggestion,
and may contradict any other lints (including other categories). Lints should be considered
on a case-by-case basis before enabling.

Some use cases for
restrictionlints include:- Strict coding styles (e.g.

clippy::todo). - Preventing panicking in certain functions (e.g.
clippy::unwrap_used). - Running a lint only on a subset of code (e.g.
#[forbid(clippy::float_arithmetic)]on a module).
