@Jo Well I am still unconvinced of your opinion that such the strategy that I intend to adopt will fail in the long run. I'll give you my reasons for it. Firstly, we are just talking about Math Spec Languages not generalized programming languages with complex rules. I have noticed that the rules of different Math Spec Languages tend to be quite similar differing only in the syntactic sugar. After all, the functions are quite similar.

Right now sympy uses hand written parsers which has made the development process of new parsers a mess because of lack of structure and lack of standardization. All I want to achieve is a standard by which we will always be able to define new parsers should the need arise. Also, I intend to pursue development of NLP parser for sympy(quite rudimentary) so as to achieve a basic capability to match that of WolphramAlpha's. I suggest you read the thread (the part where certik points to the same topic) and give your 2 cents about my approach.
