attrubute_will_change! gets erased after assignment

Reported by Fjan | September 17th, 2009 @ 09:33 PM

This is probably not a bug, but it seems very likely to trip people up so I suggest adding a note to the documentation

Person.new
Person.name_will_change!
Person.changed  # => ['name']
Person.name = nil
Person.changed  # => []
