Yes, the parse tree is provided by the Synopsis::PTree API (C++),
while the AST is provided by the Synopsis.AST API (Python).

Not a class, but an object (a PTree::Node, representing the root node
of the tree).

Not sure what you mean by 'mapping' in this context. The source from
which the parse tree is built may or may not be dependent on platform-
specific details (system headers, say), and so will the parse tree.

I still fail to see what you are aiming at. So far it sounds pretty
academic.
