-# A TokenStream is a list of tokens, gathered during the parse of some entity
-# (say a method). Entities populate these streams by being registered with the
-# lexer. Any class can collect tokens by including TokenStream. From the
-# outside, you use such an object by calling the start_collecting_tokens
-# method, followed by calls to add_token and pop_token.
