Typing in commands -- yes it give an error, but in a shell script (even
/bin/sh) if you say 'echo asdf${barf}asdf', you get 'asdfasdf' -- at least
on my shell here. :)

Properties are always just strings -- not of any other type. An empty string
can be either "" or null. Since there are no other types here, and I can't
think of a case in using a property where you really care about the
difference between "" and null, using "" for the undefined just seems
natural.
