Description

Assume that s is a method that yields a single object:

def s(a)
  yield(a)
end

def somethingelse
  s(obj) {|a, b| [a, b]}
end

When somethingelse executes, MRI will call obj.toAry, and if toAry returns [:thing, :otherthing], a gets :thing and b gets :otherthing. In jruby, a gets obj, and b gets nil, and obj.toAry is not called.

This is tested in rubyspec/language/block_spec.rb
