## What is the purpose of the change This pull request adds support of SKIP_TO_NEXT, which will fully cover all variants of AFTER MATCH clause in SQL. This clause is important for e.g. reluctant quantifiers at the end, as after first, shortest match, all others started at the same element will be discarded.
