Please excuse my many metas in the following block :
The introspector uses (meta-meta)reflection on the
(meta)tree level. The trees are a description of the
code, therefore meta. The meta information about the
tree is a description of the description, therefore

Each meta-tree node type knows what its fields are,
thier types and is's parent classes. 
(This is happening in the treecc level I presume.)

The the generation of the persistence and
serialisation methods, sql tables and such is easy
given this tree-meta reflection, a tree node can
access it's needed information at the time of dealing
with tree instances, or the code can be generated
statically (like a database schema).

It is relativly simple to create a simple xml
serialisation given a easy to use meta model.

Please excuse my ignorance about the pnet,
there is no dis intended!
I will have to review the entire project in detail.

I found in the table of contents of the 
microsoft IL assembler some interesting items:
"Signature Type Specifications"
"    Native Type Declarations"
Are these function and data types for c? Can I
represent  the function type  of "printf" in IL?

Great! I will have to review the sources for that over
the weekend. Again I have not gotten that far yet. I
am preparing for a two week vacation and have a lot of
work to do for my day job. Hacking around on these
trees is what I do for fun :).

I will look into them pronto!
