Thanks. Yes it looks much the same, and it does use AST. This from the
"""Compile a PTL template.
First template function names are mangled, noting the template type.
Next, the file is parsed into a parse tree. This tree is converted
a modified AST. It is during this state that the semantics are
by adding extra nodes to the tree. Finally bytecode is generated
the compiler package.
