Idempotent loop body
Reports loops whose second and all subsequent iterations do not produce any additional side effects other than the one produced by the first iteration, which can indicate a programming error.
Such loops may iterate only zero, one, or infinite number of times. If the infinite number of times case is unreachable, such a loop can be replaced with an
if statement. Otherwise, there's a possibility that the program can get stuck.
