    %h2.center Goal
    %p
      The goal is to execute (not interpret) object oriented code without external dependencies,
      on modern hardware.
    %p
      This means compiling dynamic code into binary. Using type knowledge at run-time we
      optimise and cache method dispatch for know types.

      As the system is 100% in ruby, the ultimate goal is to carry on the compilation at run-time,
      ie after the program has started.
      %b No interpretation.
    %p
      Using the compilation method on it's own runtime (and bootstraping with an exising ruby),
      it is possible to write the whole system in a dynamic oo language (ruby), thus
      %b removing the two language problem
      (having to choose between nice and fast)

      Work is progressing on the ruby compiler. This uses a pure
      %a{:href => "https://github.com/whitequark/parser"} ruby parser
      to create:
    %ul
      %li
        An Object model of
        = succeed "," do
          %a{:href => "/typed/parfait.html"} classes, types
        methods and basic types.
      %li Methods for every type (may be several per class)
    %p
      The lower level, strongly typed layer is
      = succeed "." do
        %a{:href => "/typed/typed.html"} finished
      While it has well known typed language data semantics,
      it introduces several new concept:
    %ul
      %li Object based memory (no global memory)
      %li Object oriented calling semantics (not stack based)
      %li Inline method caching.
      %li
        %a{:href => "https://github.com/ruby-x/ruby/tree/master/lib/register", :target => "_blank"} Register machine abstraction
      %li
        Extensible instruction set, with arm implementations
    %p
      An abstract risc like register level defines some abstraction from the actual hardware. The
      type compiler compiles to this level, but a mapping to Arm is provided to produce
      = succeed "." do
        %b working binaries
    %p
      There is also an interpreter (mostly for testing) and a basic
      %a{:href => "https://github.com/ruby-x/rubyx-debugger"} visual debugger
      which not only helps
      debugging, but also understanding of the machine.
