This file is valid Forth source code, but also a Markdown file thanks to Forth allowing to define new syntax. Anything outside fenced code blocks will be skipped by the Forth compiler/interpreter. This allows code to be written in the literate programming style.

Note: This will be a contrived example, but hopefully illustrates some real-world trade-offs.
Example scenario: Suppose you're an independent web developer, and a client asks you to prototype a redesign of their website header. You'll be paid for your time, and if the client likes it, you'll be hired to do the full implementation. Your incentive is to show the client a quick, functional demo of the updated header. The problem is that quick and functional tend to be mutually-exclusive.

Imagine this totally hypothetical situation: You're in a boring meeting without internet, play a round of nethack as a rogue, and come across a dwarvish mithril-coat. Should you replace your current leather armor? On the one hand, mithril sounds pretty nifty. On the other hand, it seems a bit out-of-character for a rogue to wear full plate armor, so surely there are some good reasons to keep the leather?
Luckily, you are a professional developer, so you have a local copy of the games' source code.
