As for "complete state": irb needs a full ("complete") expression before it
can run eval(str). It is intelligent enough to keep reading until the
expression can be eval'ed, e.g. if you enter 
  class Foo
it will ask for input until it sees a matching 'end'.
Note that irb's lexer is not perfect so this might fail occasionally.
