Step1 is to have a derivative metafunction which computers the nth derivative of
a function at compile time.

In order to do that, I need a mathematical language to write my functions.

so I have constants, variables, basic_functions and user-defined functions that are terminals of my language

   f(x) = log(x);

   g(x) = derivative(1, f, x);

   g(x) will be 1/x; 

I should manage to run derivative purely in compile time.

Later, I will look at stochastic and partial differential equations and write functions to solve them analytically whenever possible...

proto will help me define terminals, the grammars for what are acceptable expressions.
