That bit me already.  I'm not sure why ARGUMENTS is an expanded type.  I
have to read the Typing_policy to better inform myself.

Ahh ... There goes my multi-user DBMS ... I guess it'll just have to be
single-user now <grin>.

I'm using it already, although it's also not being maintained.

What is perhaps most confusing is the status vis-a-vis SmartEiffel.  I
know you guys converted its wiki, so there's still a lot of references
to it which presumably you haven't had time to clean up.  But the
original project's website still exists, even though it hasn't been
updated for seven years, but there's no clear "hey, we're not
maintaining this anymore".
