Why is Uglifyjs tripping over all files where this code is defined?

Question

JavaScript

Subject
https://gist.github.com/icodejs/4141501
Writes this:

Unexpected token keyword «function», expected punc «,»

The code itself is completely identical to the gist. Used in qtip2, jquery.cookie ... etc. There are no errors, or they are quite popular. The coal version is the latest. Nobody faced?
