Q: What is a spaghetti program?

A: Any program that is not fully nested in a manner

how to create spaghetti control flow?
- conflate control flow with data
- use IF…THEN…ELSE conflated with non-local variables
  - IF…THEN…ELSE is too low level - invent better syntaxes for conditional use-cases
    - e.g. CASE on TYPE is OOP method calling (conditional control flow without explicit IF…THEN…ELSE)
  - IF…THEN…ELSE was invented to handle conditional function values, not control flow, called COND in McCarthy’s Lisp 1.5
- allow hidden control flow dependencies
- use CALL/RETURN in clever ways
  - CALL/RETURN was not invented to support functions
    - it was invented to save code space
Drakon tutorials for pure control flow, structured
Structured Programming
- localized, only, nesting of control flow for synchronous programs
Lambdas
- attempt at localizing / nesting data
- free-for-all for control flow - function calling is not guaranteed to be nested
Packages
- greasy attempt to nest names - knee-jerk band-aid instead of fixing true problems
- nests names, but not control flow
0D
- nesting of control flow - isolation of control flow
- step 1 - isolate nodes
- step 2 - nested architecture (Structured Message Passing)
Structured Message Passing
- nesting / layering of message passing architecture
CALL RETURN Spaghetti

Programming Simplicity all welcome, I invite more discussion of these topics, esp. regarding Drawware and 0D
