Fabian Zaiser	81821acd59	Implement lint that checks for unidiomatic unwrap() (fixes #1770) ... This checks for things like if x.is_some() { x.unwrap() } which should be written using `if let` or `match` instead. In the process I moved some logic to determine which variables are mutated in an expression to utils/usage.rs.	2018-06-08 05:29:25 +02:00
