Unfortunately if any error handler happens to use the C version of the
tostring function (lua_tostring) to display the error object, as in the
case of the lua command line interpreter for uncaught exceptions,
__tostring will not be honored.

facing a dilemma of whether to wait until the workshop (8 months away)

times recently.
