Issue #8357 has been updated by marcandre (Marc-Andre Lafortune).

    Enumerable === [] # => false, should be true

Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


Array < Enumerable # => true
Enumerable.send :prepend, Module.new
Array < Enumerable # => nil
Array.ancestors.include? Enumerable # => true

Same thing happens in 2.0.0-p0.

Possibly similar to what's happening in: http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/53106
