Types versus architecture
There are three invariants in a software system: Code Types The architecture One old rule is: more types, less code. This is because the less "sophisticated" type provides less "support" to the code, and therefore you need more code to keep things in control. Another way to put this is that the invariants provided by the use of more types allows the code to be more simple. For example, long ago I experienced this type of code simplification with the use of the record/struct moving to C and Pascal from early basic and FORTRAN (and assembly). And again with classes and objects moving to C++. And again with variant types and later monads with functional programming. Another rule is: better architecture, less code. I have repeated this mantra for many years and yet thinking about it, I am not even very sure I have a good definition for architecture. I use to say: 'architecture is what does not change in the system'. Now maybe I should say: 'it's what d...
