[antlr-interest] Antlr 3.2 vs. Bison 2.4.2+Flex 2.5.35 Speed/Memory

Very interesting. The token stream in v3.2 I don't think but first tokens by default, but it still buffers all of the input characters...

That said, I am going to implementing some of this stuff with a more fly weight pattern in v4. However, it sounds like you need to implement your own token stream that discards the tokens at certain points.
