+      ./vaults.des: line 110, pos 9 : syntax error at level.depth
+    
+    Because core_func_retval() wasn't declared, it was defaulting to
+    return type **int**. So you could get, for instance, return
+    value 361 (which is 'i' + 256 .. high bits of the return value
+    were being kept, instead of discarded as they might for a narrower type).
