    merging this. 
    @dianfu could you create a JIRA for the `Optional` after `greedy` to track interest in
that case.

> Greedy quantifier will try to match the token as many times as possible. For example,
for pattern {{a b* c}} (skip till next is used) and inputs {{a b1 b2 c}}, if the quantifier
for {{b}} is greedy, it will only output {{a b1 b2 c}}.
