The append() syntax works, if you use the other definition of safedict
(*). There are more than one way of defining safedict, see the subtle
differences between the two versions of safedict, and you'll be glad
more than one version has been posted. At any rate, what has been
presented is a general idea, nitpicking details is kind of out of
place. Programmers know how to modify a general receipe to suit their
actual needs, right?

(*) In some cases, people do not want to create a dictionary entry when
an inquiry is done on a missing item. In some case, they do. A general
receipe cannot cater to the needs of everybody.
