Causes side-effect on jshint

[leebyron]

If I include es6-transpiler in my gruntfile, then a previously passing jshint now fails with a bunch of cryptic error messages which look like:

   src/List.js
>> 'undefined' is defined but never used.
>> 'undefined' is defined but never used.
>> 'undefined' is defined but never used.
>> 'undefined' is defined but never used.

have you seen this before? Even simply adding require('es6-transpiler') somewhere in the gruntfile triggers this.

+1. There are even more sides to this - seen here #68
