Who is this book for?

This book is intended for developers who wish to understand how Letlang is designed.

Letlang is in an early stage, the design is quite finished and the implementation is a work in progress. Anyone interested in the language might find some interest in this book.

What can you expect from this book ?

This book introduces the features of Letlang, their syntax, and some implementation details.

Because Letlang is currently in the implementation phase, no more feature will be added. This book is a good place to find out about those features, how they work, and how to use them.

What are not the goals of this book ?

This book is not a tutorial and does not provide any documentation about the future standard library.

This book isn’t a specification as well, but a first draft of the future documentation.

If you are interested in the specification (also a work in progress), they are currently being written as Letlang Enhancement Proposals.
