I raised that argument, and found out I was literally the only one that 
thought that was a good idea. I'm happy to hear that I'm not 100% alone, but 
it's not happening in the Standard.

Indeed, it's been suggested that:

([1,2,3], [7,8,9]) is a good idea a two-dim. array.

Supposedly, this will be the provence of style tools and rules.
