---------------------------------------------------------------
Currently a pattern like: {{Pattern.<Event>begin("st").followedBy("end");}}
will throw an {{NPE}}. Because a null condition with a skip-till-next
continuity will be wrapped into a NOT condition which will then try to call
filter() on the null condition.
