Itcl - the [incr Tcl] extension

FinalizeCreateObject converts all TCL_ERROR codes

into reraised [return -level 2]

which is implicitly [return -level 2 -code ok]

which makes no sense at all.

It goes to the trouble of calling Tcl_GetReturnOptions()
then throws it away.  It has some bizarre dance where
the value of "result" is only captured from Tcl_SetReturnOptions()
for certain kinds of classes.

The whole exercise is just a giant red flag that YOU'RE DOING
IT WRONG.

Then up in clazzUnknownBody we have to [catch] the TCL_RETURN
is order to properly convert it back to a TCL_ERROR.

But the whole clazzUnknownBody invocation of handleClass is
also broken -- at least in the case where we're using unknown
in the TclOO style of reacting to an unknown method.  We
react to a missing method by creating a new instance of the
class with the name of that method?  WTF?

Broken broken broken broken.
