Module parse failed: Invalid labeled declaration

An error occurs during the build:

ERROR in ./node_modules/js-xpath/src/parser.js
Module parse failed: Invalid labeled declaration (423:26)

Thanks for the report, @vsbeats. I'm not sure when we'll get around to fixing this since it's not currently inhibiting our usage. Pull requests are welcome!
