+- Keep the number of (anonymous) arguments "reasonably" low:

+    + 4 is suspicious but may be reasonable
+    + 5 is _very_ suspicious and probably unnecessary

+        1. revising abstractions, or, if not practical
+        2. creating a public record specifically for the purpose of passing
+           many arguents, which simulates labeled arguments. For an example see
