      Description

      Using an AST-vistor find all lookahead assertions and for each one report an issue if the sub-automaton spanned by lookahead.element and lookahead.endOfLookaheadState does not intersect the prefix of the continuation automaton and the continuation automaton does not intersect the prefix of the sub-automaton (the latter should not be considered if we know that the regex is only used as a full match).
