Library for parsing type expressions and/or property types defined using var PHPDoc annotation almost as defined in PSR-5 specification draft, just a little bit more permissive. It also supports merging two (or more) types like int|string -> scalar or string[]|int[] -> scalar[]
PSR-5 ABNF: https://github.com/phpDocumentor/fig-standards/blob/master/proposed/phpdoc.md#user-content-abnf
