Ha, right ! Forgot about domain_of. It fixes this indeed.

Concerning the other approach, I guess it boils down to have terminal of 
the given function object laying around?

terminal< exponent_ > exponent  ={{}};

How does it scale with a large number of function object (say > 300) in 
term of compile time ?
Is there any advantage over make_expr ?
