CROSS LATERAL APPLY possible?

[xdbr]

Impressive work @mithrandie and such a fanstastic library!

I was wondering whether the following scenario is already possible or how difficult it would be to implement something along these lines:

Example: Join Each Product to Its Tags
Suppose you have a table:

products
---------
id   name       tags
1    Phone      electronics,mobile
2    Laptop     electronics,computer
3    Shoes      fashion,footwear

You want to get one row per tag per product:

SELECT
  p.id,
  p.name,
  s.value AS tag
FROM
  products p
CROSS APPLY STRING_SPLIT(p.tags, ',') AS s;

id	name	tag
1	Phone	electronics
1	Phone	mobile
2	Laptop	electronics
2	Laptop	computer
3	Shoes	fashion
3	Shoes	footwear
