Writing Functionally Pure Code

Is all my code going to be pure?

Nope. No program can be composed 100% of pure code because every program must do I/O work, which is inherently stateful. Most programs also need to carry around some amount of internal state, to one degree or another. The goal of functional programming, then, is to maximize the proportion of pure code to impure code in your program.

Pure vs. Impure

What does it mean for data and code to be pure? The short answer is that pure things are immutable, but this is not quite accurate: all pure things are immutable, but not all immutable things are pure. Pure things are not only unmodifiable but also definitional.

TrafficLight control/layout/property drawer: Adds a new editor control that draws lil Traffic Lights in the inspector. its really useful for visualizing state. For example, checkboxes can be hard to read at a glace, but a Red or Green status light is easy! Recommend you use the attached package, as it has all the icon image files.
// Non Editor code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public abstract class TrafficLightAttribute : PropertyAttribute
{
public bool DrawLabel = true;
public string CustomLabel;
public bool AlsoDrawDefault;
