+ * Raku (Perl6) Lexer for Scintilla
+ * ---------------------------------
+ * ---------------------------------
+ * 06-Dec-2019: More Unicode support:
+ *              - Added a full scope of allowed numbers and letters
+ * 29-Nov-2019: More  highlighting / implemented basic folding:
+ *              - Operators (blanket cover, no sequence checking)
+ *              - Class / Grammar name highlighting
+ *              - Folding:
+ *                - Comments: line / multi-line
+ *                - POD sections
+ *                - Code blocks {}
+ * 26-Nov-2019: Basic syntax highlighting covering the following:
+ *              - Comments, both line and embedded (multi-line)
+ *              - POD, no inline highlighting as yet...
+ *              - Heredoc block string, with variable highlighting (with qq)
+ *              - Strings, with variable highlighting (with ")
+ *              - Q Language, including adverbs (also basic q and qq)
+ *              - Regex, including adverbs
+ *              - Numbers
+ *              - Bareword / identifiers
+ *              - Types
+ *              - Variables: mu, positional, associative, callable
+ * TODO:
+ *       - POD inline
+ *       - Better operator sequence coverage
