I just asked the same basic question within the past week or so, actually.  
Use instance_eval(&procvar), e.g.

class Foo
  def initialize
    @var = 1
  end
 
  def call(p)
    instance_eval(&p)
  end
end
 
p = proc { p @var }
foo = Foo.new
foo.call(p)    # => prints '1'

-- 
self.instance_of? RyanTarpine     # => true
