    Alternation-num-ranges

    Set of numeric ranges in an alternation.

    Signature
    (alternation-num-ranges alt) → ranges
    Arguments
    alt — Guard (alternationp alt).
    Returns
    ranges — Type (num-range-setp ranges).

    This is the union of the sets of numeric ranges from all the alternatives (i.e. concatenations) that form the alternation.
