The "Python Way (tm)" seems to be to insist on explicit conversions between
basic types, so implicit conversions at the ORB interface would be inconsistent.

Whether or not a rapid prototyping scripting language should insist on having
the programmer continually perform basic type conversions is another debate.

The next release of Fnorb will have these type checks, so that instead of
performing the obvious conversion, it will just give up and fall over with an
exception. Just like Python itself. Now *that* is progress. Sigh.
