The problem is that you really can't. Tex isn't semantic, it's visual. Even matrix transposition, one of the most basic things in linear algebra, is written differently by different people. I've seen plenty of people just write ^T, which requires an amount of contextual awareness a parser just cannot have to differentiate from just raising something to the power of "T".
