Binding#eval __LINE__ and __FILE__ in Ruby 1.9.1

[trans]

Ok. One last question in today's debugging for 1.9 session.

Using Bindging#eval, __LINE__ and __FILE__ always appear the same:

  binding.eval('__FILE__') #=> "(eval)"
  binding.eval('__LINE__') #=> 1

Do we not want the __LINE__ and __FILE__ of the binding call in the
binding's context? That is what 1.8.7 does.

So, is it a bug? Or has this been changed for some reason?
