Would this be usable with a RoR app?

I am not certain if RoR core needs Symbol#to_proc ... but, it would be nice
to use enumerable-extra in my Ruby coding in RoR. I am just iffy about
trying it cause I am not certain if I would break my RoR app because I
installed the gem and the gem overirides Enumberable#map and so forth.

Thanks :)

Sorry if it seems like a newb question, but I am learning both Ruby and RoR
at the same time -- so, in a sense I am a newb :-P
