}Expand description
A single component of a character class set.
An empty item.
Note that a bracketed character class cannot contain a single empty item. Empty items can appear when using one of the binary operators. For example, [&&] is the intersection of two empty classes.
A single literal.
A range between two literals.
An ASCII character class, e.g., [:alnum:] or [:punct:].
A Unicode character class, e.g., \pL or \p{Greek}.
A perl character class, e.g., \d or \W.
A bracketed character class set, which may contain zero or more character ranges and/or zero or more nested classes. e.g.,[a-zA-Z\pL].
A union of items.
Return the span of this character class set item.

Tests for self and other values to be equal, and is used by ==.
Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
