OT:

All true, but also consider the fact that === requires one to remember 
what it means (=== vs. ==), which is not particularly intuitive (as 
opposed to is_a?, which is a term most students get drilled into their 
heads pretty much the first day of their first OO programming course). 
The confusion is further compounded by the fact that (if I remember my 
JS correctly) the functionality of === and == in Ruby are exactly 
reversed from their functionality in JavaScript.
