Hi Ajay

well ESS has such a facility.

However, I think Mathematica has a super scheme: unbalanced brackets show up
in red, making them obvious.

This is particularly good for spotting wrongly interleaved brackets, as in

([ blah di blah )]

<note bracket closure is out of order>

in which case both opening braces are highlighted in red: and the system won't
accept a newline until the closures are all correctly matched.

Would anyone else find such a thing useful?

Could the ESS team make something like this happen?
