typechecks: just say no! (was Re: Determining Types)

[Skip Montanaro]

One place that I've actually found typechecking useful is at the boundary of
my XML-RPC server.  If I'm expecting a string input (say, the name of a
band) and someone on the other side inputs "311" to a Perl-based website
which then passes the query to my server, I get an integer that I have to
coerce back to a string.  In my comments I call it a "Perl guard". ;-)
