Log:	Remove dead code. Q: Where does it come from? A: from CPython:
	Python/ast.c Q: Why this code in CPython? A: In file
	Grammar/Grammar, keywords and operators are enclosed in quotes
	('def', '+='); grammar.c contains logic to create the various
	tokens, and separate keywords from operators; probably in old
	ages the same code was used to parse the Python language as well.
