// The new assembly support in Solidity makes writing helpers easy.
// Many have complained how complex it is to use `ecrecover`, especially in conjunction
// with the `eth_sign` RPC call. Here is a helper, which makes that a matter of a single call.

Writing node modules with voxel.js

This is a short guide that will teach you the workflows that have been figured out by the voxel.js community for writing node modules + sharing them on NPM and Github. It is assumed that you have a basic understanding of JavaScript, github and the command line (if not you can check out an introduction to git and the command line or learn JS basics from JavaScript for Cats)

The voxel-tower repository on github contains all the example code from this guide.

A monad is a fancy word for a generic type of the form MyMonad<T> (a generic type of arity 1).

A monad is special because it adds 'special powers' to the T that it wraps. These 'special powers' won't sound very special to an imperative programmer, so you have to squint to see them but bear with me.

• IEnumerable<T> is a monad that gives values of type T the special power of nondeterminism, or the ability to 'be' multiple values at once.
• Nullable<T> is a monad that gives values of type T the special power of nullability, or the ability to be absent.
• Task<T> is a monad that gives values of type T the special power of asynchronicity, or the ability to be used before they are computed.

The trick with monads comes when you want to play with the T values, because they are inside another type. C# introduced language changes to make dealing with values inside these monads easier:
