(div-euclid! place ..args)
  place: a place
  args: zero or more forms

Performs in-place Euclidean division or reciprocation.

(div-euclid! x 11 12) is equivalent to (= x (div-euclid x 11 12)), except that x is only evaluated once.

This means that with only one argument, (div-euclid! x) replaces x with its reciprocal, (div-euclid 1.0 x).
