Remove indexOf from Enumerable#include because it uses strict equality
Reported by John-David Dalton | June 24th, 2008 @ 05:43 PM | in 1.6.1
Garret Smith pointed out that the use of this.indexOf uses strict equality if its being used on an array. So I have patched the method to remove this usage.

Use of indexOf here is for perf reasons. (And yes, this would need real benchmarks.)
Other than that, there's no reason for this to return incorrect results.

It certainly is weird to perform another loop if "indexOf == -1". Why can't we just return its result if method is present?

Ya Garrett mentioned that too.
Though now that I look at it.
If it failed the "indexOf" (which could be caused by it not meeting the strict equality), it will be looped again manually and it should pick up the match that way. Was this done by design?
If so and the "indexOf" is more of a performance boost (I can see where this ticket is totally not needed).

This is one of the reasons why we need a better documentation.
It's often not clear whether something was made intentionally or by mistake : )

I am marking this invalid because if it fails the strict equality of indexOf it falls back on the traditional for loop scan.
