It's more limited than what you'd ideally want: pattern matching in function definitions. This makes walking ASTs a breeze.

Edit: And inline pattern matching for values returned from expressions and function calls (similar to destructuring, but more powerful).

I would say what C#12 does is already quite good, likewise for Swift.

Perfection is the enemy from good.

Those I can use at work, ML derived languages not, even F# is an uphill battle in most shops.
