I like the idea. It will require changes on parsing for sure, but the result is a more freeform text, less like a real list.

I think this could be applied to all other list expressions like arithmetic or array operations, too. At least it would be good to maintain a uniform format to define lists.

Hmmmm. That one's good, but I'll have to think further to see if I spot anything.
