The advantage to the block(nle) ... end form is you can pass the
non-local exit as a parameter to functions, so it can serve as an

Caught in a whirlpool,  | As dawn-rays tickle our toes, the dew soothes
A quartering act:       | Our blistered soles, and damp bones stir
Solitude or society?    | As crimson cracks under the blue-grey sky.
