if you cannot Dwell which has a rule, item to it, dismiss it, but don’t h2o it down right until it becomes meaningless.

Readability, avoidance of faults. There are better Command constructions for human beings; goto is for machine generated code.

Use algorithms which can be made for parallelism, not algorithms with needless dependency on linear analysis

This needs to be weighed towards iostreams benefits of extensibility to deal with person-described forms, resilient in opposition to safety violations,
