Introduction

The Calypso Book is a guide on how to write code in Calypso.

Currently this guide will not describe the Calypso build tool and command-line interface as those are not yet fully designed (and they may get their own book eventualy).

Notation

Calypso code will be written in code blocks like this:

fn main() ->
    println("Hello, world!")
end

Things to look out for or further explanations of things may be provided in notes like this:

Note: This is a note!

Or in warnings like this:
