I'm still trying to track down the exact problem, but I'm running node 4.4.6 and I just tried to uglify your package and got an error. I think it was having issues parsing 'let', so I think I need to upgrade my node to 5 in order to actually uglify your code. Will it be a requirement to use node 5 in order to use your lib? if so, it should be indicated somewhere.
