What you are talking about (something which not only interprets TeX input,
but understands its mathematical significance _from the context_ is not hard
interpretation of both notions of /pi on my [history and] philosophy of mathematics!)

Therefore, since the question was raised on the tugindia list,
I naturally interpreted the question as pertaining to something much
simpler: a desire to enter a formula with parameters once and then reuse it
for different values of the parameters. (That was the example specified.)
This can be achieved by embedding Maxima code within a TeX file using battex.

Best,
