The production
NonemptyClassRangesNoDash::ClassAtomNoDash-ClassAtomClassRanges evaluates
as follows:
1. Evaluate ClassAtomNoDash to obtain a CharSet A.
2. Evaluate ClassAtom to obtain a CharSet B.
3. Evaluate ClassRanges to obtain a CharSet C.
4. Call CharacterRangeOrUnion(A, B) and let D be the resulting CharSet.
5. Return the union of CharSets D and C.
B.1.4.1.1 Runtime Semantics: CharacterRangeOrUnion Abstract Operation
1. If Unicode is false, then
a. If A does not contain exactly one character or B does not contain
exactly one character, then
i. Let C be the CharSet containing the single character - U+002D
(HYPHEN-MINUS).
ii. Return the union of CharSets A, B and C.
2. Return CharacterRange(A, B).

Term[U] ::

The production Term::QuantifiableAssertionQuantifier evaluates the same as
the production Term::AtomQuantifier but with QuantifiableAssertion
substituted for Atom.
The production Assertion::QuantifiableAssertion evaluates by evaluating
QuantifiableAssertion to obtain a Matcher and returning that Matcher.
Assertion (21.2.2.6) evaluation rules for the Assertion::(?=Disjunction)
and Assertion::(?!Disjunction) productions are also used for the
QuantifiableAssertion productions, but with QuantifiableAssertion
substituted for Assertion.
