HI Dongfei,

I am interested in it. But what the plan is exactly ? How you are going to do it
for say expressions involving trigonometric terms ? For polynomial expressions
things are manageable, how you are going to parse other complex expressions ?

BTW how you are going to take care of algebra at many places ?
