Backport #1723: respond_to? vs. to_ary

Added by zverok (Victor Shepelev) about 17 years ago. Updated over 15 years ago.

Description

=begin

class with respond_to? redefined

class A
def respond_to?(m); false end
end

x = [A.new]

deconstructing iteration

x.each do |a, b| p [a,b] end

It outputs [nil, nil], while [#<A:0xb5c9d0>, nil] is expected. If I comment out respond_to? in A, all works as expected
