Flusspferd

The getter/setter member of property_attributes (see source:include/flusspferd/property_attributes.hpp ) is of type boost::optional<function const&>. Thus the function object is not owned by property_attributes and code like this is wrong:

property_attribues foo() {
  function foo = ...;
  return property_attributes(no_property_flag, foo);
}

property_attributes should copy the function object (=> own it).
