    This unfortunately is significantly longer to execute than the boolean OR. The grep has to test every value, whereas the if statement uses short-circuit boolean logic to stop testing values as soon as a match is found.

      "significantly"? Maybe a significant factor longer, but if the OP was even considering writing it in a long || ... || ... ||, there aren't enough elements to make it significant in absolute terms.
