So turns out I was checking out your library and found out this typo.
I'm wondering why nothing that uses the lib broke on your end as a git blame shown this change dates to Jan 11, but you might need some tests around this feature.
fix typo on extend function
Thanks for your PR. Actually, i just saw that wasn't the only problem, the extend method didn't extend the prototype of the module, so the function was essentially useless and broke all plugins. Apparently not a lot of people use plugins, so i guess that's why nobody noticed. Thanks again!
