$< is used with map in the following code.

Is $< enumerable?

$<.map{|l|p (0..9).to_a.repeated_permutation(4).count{|m|m.inject(&:+)==l.to_i}}

and `$<.class.ancestors #=> [ARGF.class, Enumerable, Object, Kernel, BasicObject]` — Yevgeniy Anfilofyev, May 27 '14 at 12:02

Yes. It's an alias of ARGF which inherits directly from Object and includes Enumerable.
