/**
 * Evaluates a nondet + oneOf() + body expression, which picks a value from a
 * set and evaluates the body with that value. If the body evaluates to false,
 * it retries with the next position in the set until it finds a true value or
 * exhausts all positions.
 *
 * - If the set is empty, it returns false.
 * - If the set is infinite, it picks a random value from the range
 *   [-2^255, 2^255) for each position.
 * - If the set is to big (bigger than QUINT_RETRY_NONDET_SMALLER_THAN), it
 *   does not retry and returns the first value picked from the set.
 *
 * @param name - The name of the nondeterministic expression.
 * @param cache - A cached value to store the picked value.
 * @param setEval - The evaluation function for the set from which to pick a value.
 * @param bodyEval - The evaluation function for the body of the let-in.
 * @returns An evaluation function for the nondet let-in expression.
