No, not really. You've always been able to do it, with
Object#instance_eval.

tim@zaphod:~$ ruby -v
ruby 1.6.7 (2002-03-19) [i386-linux]


irb(main):001:0> class Foo 
irb(main):002:1>   def bar
irb(main):003:2>     @bar
irb(main):004:2>   end
irb(main):005:1> end
nil
irb(main):006:0> f = Foo.new
#<Foo:0x40271c60>
irb(main):007:0> f.instance_eval{ @bar = 7 }
7
irb(main):008:0> f.bar
7
irb(main):009:0>
