Ah, of course. Thanks for noticing that.

I thought about this for a while, and the best testing mechanism seems 
to be just turning the "print object" option on by default and running 
the entire testsuite, otherwise this test will be very specific to the 
-var-create mechanism.

value_actual_type is called from 3 different places IIRC.

If we're thinking about a regression coverage test, then i agree that a 
test is appropriate in this case, so we can be sure it will never happen 
again.
