Subject: Enumerable#select used to return actual values

I'm pretty sure select used to use the actual value of the called block, 
instead of treating it as just a truthy/falsey boolean.  I know this is 
unconventional, but it's a really nice, compact way of expressing map and 
filter in one shot, like list comprehension:

(1..10).select { |a| a * a if a > 5 }

Was it ever there, or did I just have a dream about it?  It's easy to 
implement... just wondering.
