        reliability
        Bug

          Why is this an issue?

          There is no reason to re-assign a variable to itself. Either this statement is redundant and should be removed, or the re-assignment is a mistake and some other value or variable was intended for the assignment instead.

          Noncompliant code example

          def set_name(name)
            name = name
          end
          

          Compliant solution

          def set_name(name)
            @name = name
          end
