Release Notes: This release drops support for generating line numbers as text directly into the pyAST. Instead, now pyAST consists of pyPEG.Name objects for the names of the non-terminal symbols. pyPEG.Name is a class derived from Python's str class. Additionally, it has a .line attribute, which contains the line number where the corresponding non-terminal was found. Memoization has been added, so pyPEG is a packrat parser now (optionally).
