final class KeywordTable

Restricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.

The words SQLite's tokenizer turns into keyword tokens.

Several words share a token: the join words are all JOIN_KW, and LIKE, GLOB and REGEXP are all LIKE_KW. Which keywords may fall back to identifiers is the grammar's business.
