Subject: binding in ruby1.9

Could someone explain why this code does not work in ruby1.9 and  
possibly provide a workaround. The end goal is to be able to pass a  
binding to an ERb result method that provides a limited set of  
variables to the ERb template evaluation.

 > cat a.rb

obj = Object.new
class << obj
   attr_accessor :foo
end
obj.foo = 'the foo method'
eval "puts foo", obj.__send__(:binding)

 > ruby a.rb
the foo method

 > ruby1.9 a.rb
a.rb:7:in `eval': undefined local variable or method `foo' for  
main:Object (NameError)
	from a.rb:7:in `eval'
	from a.rb:7:in `<main>'

 >ruby1.9 --version
ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-darwin9.6.0]
