Quick question:

I noticed Ter say this:

... was there a decision made at some point to have the lexer not slurp the entire input at once like v3?   If so I'd like to read more about pros and cons of that, and whether that facilitates more interactivity between lexer and parser... was there a thread on that at some point?

Thanks,
