+A representation of the ruby code.
+
+## Concrete Syntax tree
+
+Ruby is parsed by the parser gem (big thanks to whitequark). Own attempts at
+this task have failed utterly, because ruby is a _huge_ language (and not well
+defined at that)
+
+Alas, the parser gem creates an abstract syntax tree, meaning one class is used
+to represent all node types.
+
+Imho object oriented languages have a class system to do just that, ie represent
+what we may loosely call type here, ie the kind of statement.
+
+The ruby layer is really all about defining classes for every kind of statement,
+thus "typing" the syntax tree, and making it concrete.
+
+## to Vool
+
+In our nice layers, we are ont the way down to Vool, a simplified version of oo.
+
+It has proven handy to have this layer, so the code for transforming each object
+is in the class representing that object. (As one does in oo, again imho).
+
+## Parfait objects
+
+The compilation process ends up creating (parfait) objects to represent
+things like classes, types and constants. This is not done here yet, but in
+the vool layer.

+Vool is a layer with concrete syntax tree, just like the ruby layer above.

Subject: [PATCH 12/25] starting to fix builtin

start at Object get_interna_word
using the pattern to replace the whole risc method with a single mom instruction. Copying the original risc code into the instrucitons to_risc
also adding some very basic tests

Subject: [PATCH 18/25] Move builtin wholesale to Mom

Since Builtin generates risc, just like mom instructions, it was a design mistake to put builtin into risc in the first place. Now that borders are coming more into focus, it make much more sense to have the builtin in mom.
In fact the instructions should be moved out and a seperate invocation mechanism used , so functions can be parsed, not generated (wip)

 # Builtin Testing
 
-Mostly testing that
+At the Module level (word/object/integer) mostly testing that
 - functions exist
 - they compile
 - basic length tests (no "contents")
 
+Minimal tests for risc compilation, and again length only (should be array too)
+
 Functionality is tested by interpreter over in interpreter dir

Subject: [PATCH 25/25] And we are green again

After having over 600 failing tests at one point, this does feel good.
Even better, most of the risc/interpreter tests where i didn't change anything came gree without changing the tests. ie we have binary compatibility.
