-# DWARFv5 type unit - to test both v4 and v5 type unit support.  This test
-# doesn't really need templates - two local variables would've sufficed
-# (anything that references the type units) but I was working on something else
-# and this seemed minimal enough.
+# To various scenarios, the test uses a mixture of DWARF v4 and v5 type units,
