+# SETs(TARG), XPUSHn, XPUSHu,
+
+# Unsafe to set if the ppcode uses dTARG or [X]RETPUSH[YES|NO|UNDEF]
+

+
+# Additional mode of failure: the opcode can modify TARG before it "used"

+# If the target coincides with one of the arguments ==> kaboom.

+# each repeat not OK too due to list context
+# pack split - unknown whether they are safe
+# sprintf: is calling do_sprintf(TARG,...) which can act on TARG
