It does, because
irb(main):004:0> Range.instance_method :to_ary
NameError: undefined method `to_ary' for class `Range'
from (irb):4:in `instance_method'
from (irb):4
from /usr/bin/irb:12:in `<main>'
and, as our friend would have learned a few days back if he followed
the advice to use set_trace_func to learn what's going on
irb(main):015:0> o = Object.new
=> #<Object:0x802a7a80>
irb(main):016:0> def o.to_ary; [1,2,3,4] end
=> nil
irb(main):017:0> a, *b, c = o
=> #<Object:0x802a7a80>
irb(main):018:0> a
=> 1
irb(main):019:0> b
=> [2, 3]
irb(main):020:0> c
=> 4
