    AST** -- With the lexer in place, we can talk about parsing
    techniques and basic AST construction. This tutorial describes
    recursive descent parsing and operator precedence parsing. Nothing in
    Chapters 1 or 2 is LLVM-specific, the code doesn't even import the
    LLVM modules at this point. :)

    a JIT, we'll dive right into it and show you the 3 lines it takes to
    add JIT support. LLVM is also useful in many other ways, but this is
    one simple and "sexy" way to shows off its power. :)

    Control Flow** -- With the language up and running, we show how to
    extend it with control flow operations (if/then/else and a 'for'
    loop). This gives us a chance to talk about simple SSA construction
    and control flow.

    User-defined Operators** -- This is a silly but fun chapter that
    talks about extending the language to let the user program define
    their own arbitrary unary and binary operators (with assignable
    precedence!). This lets us build a significant piece of the
    "language" as library routines.
