This is due to said routine assuming that tokens start at 1. They don't. |

I figured something like that. If you look at the issue again, I
rewrote the text a bit, and now, ghosting over it shows the right PR :)

A trivial yacc grammar with the following tokens:
%token ABLE
%token BAKER
%token CHARLIE
The main function call fmt.Printf with the output of yyTokname (passing in the token const)
What did you expect to see?
ABLE => "ABLE"
BAKER => "BAKER"
CHARLIE => "CHARLIE"
What did you see instead?
ABLE => "tok-57346"
BAKER => "tok-57347"
CHARLIE => "tok-57348"
