Subject: [PATCH] add unit test to ensure esprima+recast WILL NOT fail
 https://github.com/GerHobbelt/jison/issues/30 (which currently still uses
 regexes for code manipulation instead of esprima+recast AST rewriting) ::
 action code in grammar doesn't expand `@label` ref inside template string
 with comments
