Expand description

Extend a type of code point to query if a value belongs to a particular Unicode property.

This trait defines methods for querying properties and classes mentioned or defined in Unicode® Standard Annex #31. These properties are used to determine if a code point (char) is valid for being the start/part of an identifier and assist in the standard treatment of Unicode identifiers in parsers and lexers.
