Add Enumerable#uniq?
Reported by Bounga | March 16th, 2011 @ 11:17 AM
Checks for Enumerable content uniqueness
Returns true if the collection has no duplicated content.
Can be called with a block too, much like any?, so people.uniq? {
|p| p.age > 26 } returns true if only 1 person is over 26.
Unit test are included.
Please test and +1 this useful tiny patch.

Took a look at the code in the last patch that you posted. I like the implementation but you were missing a test that checked a block that produced a result that wasn't unique. I added a test for this and cleaned up some whitespace errors that I was getting with your patch.
To avoid whitespacing errors in the future try the command:
git diff --check
This will tell you which files are producing whitespace errors if any.
