Obviously, yes, since in case of a big/huge source you don't have to
tokenize all the source if you have a parse error right after first
token. So the lexer should be "piped" to the parser and provides tokens
on demand. OTOH, in academical educational implementations like this
one, you may choose any way.
P.S.: I can see in forks of the project other very interesting
solutions, e.g. with using generators (`yield`) to handle scanning process.

Would it make any difference if I had tokenized all data upfront and
then I would just pass an array of all tokens to parser? Could this
approach be slower or faster than yours?
