Constant Summary collapse

UNQUOTED_VALUE_RE =

Matches exactly the values the CDDAL lexer can tokenize as a single non-string token: keywords, numbers, dates, IRDIs, local refs, and bare identifiers. Anything not matching must be emitted as a quoted string literal so the lexer can reparse it via scan_string_literal (which is UTF-8 aware via getch).
