Right now VAX has the ability to highlight matching (as well as mismatched) {} and (). Could we extend that to include []?
You've got the ability to add a closing ] so why not include that symbol in the highlighting as well.
I thought about asking you to highlight <> as well (for the STL) but those characters can be used as mathematical operators so I think it would be confusing if you suddenly got colored < and > in a condition statement like an if().
with regard to angle brackets, if you don't use templates much then this would really get confusing, since nearly all <> brackets would be used in logic or loop statements. that certainly describes quite a lot of my code.
