by default (nobody implemented ) "as" should cause a
"no specific method" exception.
[ unless we're talking about the basic primative class (e.g., <integer>,
<character> , <symbol> , <string>). In which case, the implementation
should have defined them. User defined classes; no. ]
But generally it probably is a prudent thing to do add an "as" method
that serves as the identity function toware the top of you new
hierarchy . :-)
