Crafting a Compiler from Scratch: Implementation Notes

For the past two weeks or so, I've been working on a little compiler project in C, mostly for educational purposes, i.e. to understand how a compiler really works. I'm not using any libraries, other than the C runtime library.

Introduction

I have a hand-written lexer and parser, and a simple code generator targetting

Type classes

Type classes have some advantages over Java style interfaces. One advantage is the ability to implement functions that do not need to take in an instance of the interface.

For example, (FromString v) takes in a String and returns v, and it doesn't have to take v as a parameter.

contract MyToken {
    function MyToken() {
        assembly {
            // Store the creator at storage slot zero
            sstore(0, caller())
        }
    }
    function () payable {
        assembly {
            // Protection against sending Ether

(* Good morning everyone, I'm currently learning ocaml for one of my CS class and needed to implement
   an avl tree using ocaml. I thought that it would be interesting to go a step further and try
   to verify the balance property of the avl tree using the type system. Here's the resulting code
   annotated for people new to the ideas of type level programming :)
*)

(* the property we are going to try to verify is that at each node of our tree, the height difference between
   the left and the right sub-trees is at most of 1. *)
