Redundant variable used as 'return' value

Reports variables used as return values.

Example:

# Bad practice
def foo(bar)
  result = bar + 1
  result
end

A quick-fix is available to remove those variables. After the quick-fix is applied, the result looks like this:

# Good practice
def foo(bar)
  bar + 1
end
