[Product Feedback] Automatically changing parentheses type?

Let's say I have some code...

 function bar = fu()
   bar{1,1:3} = mat2cell(ones(1,3), [1], [1 1 1])
 end`

...and I realize that I can represent "bar" as a matrix array than as a cell array. I personally feel like when I replace one of the curly braces, Matlab should ask me if I want to change the matching one via a 'tab' command. Just a thought.
