I admire your gaming my off-the-cuff example.  But no sensible producer would try to coerce that into a DW_TAG_constant.

Can't help you there; last time I used Fortran, there was only one kind of argument.  (Which can be entertaining when you pass "2" to a formal parameter that then gets modified by the callee.  Redefining the value of "2" made for a very weird debugging experience.)
