The suggestion here is incomplete; if you just follow the suggestion verbatim and remove the & on the right hand side, you get a compile error because you're comparing a reference to a value (and rustc in fact tells you to precisely revert your "fix").

Instead, the suggestion should also suggest that you dereference the left hand side:
if *v > 50
