That is just want I want; for it to throw an error and then print out the
info, but I have to define and compile my functions in csc first, so I get
the weird errors will all the numbers after them.  Is there some way to
clean up the debug output from functions that come from csc?  Is it better
to use the #!optional thing instead of case-lambda? (I have to use one of
those for the img argument at least).
