Also, the do() is superfluous here, isn't it?
It invokes some overhead (unless the optimizer squashes it out, which I
suspect....)
Of course, the whole block is superfluous.
It's an expensive no-op, like saying undef(); on a line by itself, but
doing more work.
Am I missing something here? Feeling dense. :P
