I see
  (1..10).collect {|x| x*x}
This woud be better:
  (1..10).map {|x| x*x}

The name "collect" tends to make one assume that it does
what inject does.  On the other hand, "map" describes what
it does; it produces a one-to-one mapping.

Furthermore, "collect" in Common Lisp does something
different.  OCaml and most if not all Lisp dialects use "map"
as it is used in Ruby.

And "collect" is longer.  To me, it seems senseless to use it.
