You can only change the binding of "self":

>> self
=> main
>> pr = lambda { self }
=> #<Proc:0x003ef918@(irb):2>
>> pr[]
=> main
>> obj = Object.new
=> #<Object:0x3e98a0>
>> obj.instance_eval &pr
=> #<Object:0x3e98a0>

Kind regards

Exactly what I needed, thank you. I had looked at the documentation,
but somehow missed instance_eval.
