Most of them come from Smalltalk's Iterable protocol[0]: that's the source for `select:aBlock`, `collect:aBlock`, `inject:thisValue into:binaryBlock` (Smalltalk uses `fold` when there's no starting value, and `inject` as "fold by injecting initial value"), `detect:aBlock` and `reject:aBlock`.
Smalltalk also uses `do:aBlock` where Ruby uses `each`, likely due to `do` being a keyword in Ruby.
Also, `find` is not `filter` (that's `select`, aliased to `find_all`). `find` is also `find` in Haskell[1] (and maps to Smalltalk's `detect`, also useable in Ruby).
> 'find' collides with ActiveRecord
Uh... no, ActiveRecord collides with Enumerable, I'm pretty damn sure Enumerable came first.
> how do you do filter in Rails?
What's wrong with #find? Or #where? Or #find_by_*? Same name, different namespace, different meaning. Kind-of the point.
