New lint: ref_pattern, for disallowing the ref keyword #9010
Description
What it does
I would like to have a lint that fires on any use of the ref keyword.
Lint Name
ref_pattern
Category
restriction
Advantage
Code that doesn't use it is easier to read for newcomers since they're unlikely to be aware of what it does.
Drawbacks
No response
Example
if let Some(ref foo) = *rwlock.read().unwrap() {}Could be written as:
if let Some(foo) = &*rwlock.read().unwrap() {}
