Decorator error when using `@` variables in actions

This error is produced on the current master, 396e9250c8afd5d7d7e5658951b0d89f8bd97dd9.

It appears that the legacy decorators plugin is being introduced here: https://github.com/GerHobbelt/recast/blob/master/parsers/_babel_options.ts#L29

It looks like a workaround was committed at https://github.com/GerHobbelt/jison/commit/625fcce046508ab3fde5e39f99284c16a89f49b0 but that it hasn't yet been built into dist/cli-cjs.js
