[antlr-interest] Initializing synthetic tokens?

[Jim Idle]

As in, make it a real token in the lexer, not define it in the tokens {}
section. The syntax you show, is the correct syntax for the enum - it is a
list of imaginary tokens - real tokens belong in the lexer.

Strange. I get ". . . mismatched input ':' expecting RBRACE" .  The only
syntax that seems to be recognized is

tokens { A, B }
