You get either a compile time instantiated infinite lazy sequence, or a compilation error.

My personal bar for "amount of clever involved" is fairly high when the clever either does exactly what you'd expect or fails, and even higher when it does so at compile time.

(personal bars, and personal definitions of "exactly what you'd expect" will of course vary, but I think your brain may have miscalibrated the level of risk before it got as far as applying your preferences in this particular case)
