You can "inline" (it's really not the right word) either one using
nodewrap, but it's very evil to do:

/home/user> irb1.9
irb(main):001:0> require 'nodewrap'
=> true
irb(main):002:0> p = proc { 42 }
=> #<Proc:0xb7b848d8@(irb):2>
irb(main):003:0> p.body
=> <ISeq:block (3 levels) in irb_binding@(irb)>
irb(main):004:0> class Foo; end
=> nil
irb(main):005:0> Foo.add_method :foo, p.body, Noex::PUBLIC
=> nil
irb(main):006:0> Foo.new.foo
=> 42
