Working self-contained getting-started sample for Suave Web Scripting
//==========================================
// Working fully self-contained getting-started example for Suave Web Server scripting

// Note you don't need to have _anything_ installed before starting with this script. Nothing
// but F# Interactive and this script.

// This script fetches the Paket.exe component which is referenced later in the script.
// Initially the #r "paket.exe" reference is shown as unresolved. Once it has been
// downloaded by the user (by executing the first part of the script) the reference
// shows as resolved and can be used.

DocPad: Use DocPad, GitHub & Prose as a Wiki

Use DocPad, GitHub and Prose as a Wiki

This guide will walk you through how you can use a GitHub repository to house your wiki content, have DocPad render it, and automatically update on changes. It's also really nice as we get to benefit from the github project workflow for our wiki, that is issues, pull requests, etc.

We use this workflow heavily by linking the DocPad Website and the DocPad Documentation repositories allowing us to have users edit and submit pull requests for improvements to our documentation, and once merged, the website regenerates automatically.

1. Create a new repository for your Wiki Content

/**
* @dev OpcodeChecker processes contract code to generate a bitmap of used opcodes.
*
* DO NOT USE: See the vulnerability identified by Recmo below. A patch will be provided soon.
*
* The generated bitmap can be used to enforce whitelisting and blacklisting on contract code.
* Bit n of the bitmap is set iff opcode n is used. For instance, the presence of the STOP opcode
* will result in bit 0 of the bitmap being set.
*
* A best-effort attempt is made to skip over unreachable data, but there may be false positives.

Memory as a dependently-typed effect (scroll down for examples!)

Memory as an effect

What if we treated memory as a side-effect?

Idris lets us track lots of things in the type system, in order to get errors at compile-time rather than at runtime. One of the tools that lets us do this in Idris is called Effects, and they're used to keep track of state, to manage file handlers, and lots more.

In barely 40 lines of Idris (which could be less if I had any idea what I'm
