Thanks. Yes it looks much the same, and it does use AST. This from the ptl_compile.py module: """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 into a modified AST. It is during this state that the semantics are modified by adding extra nodes to the tree. Finally bytecode is generated using the compiler package. """ -- http://mail.python.org/mailman/listinfo/python-list
