Dear Alejandro,

As this discussion is at the moment going on two lists at the same time, I
decided to answer both Alexeis opinion and this concern of you and
Vladimir in ginac-devel and I suggest that we discuss this further on one 
list (i.e., ginac-devel), which should keep things more organized.

I think GiNaC will be useful for doing this kind of unrollment.  However,
you may need to write a program that produces a C++ file that you later
compile. I.e., a code generator. Not sure if that is what you want to do.  
Using GiNaC for numerical evaluation should not be done if speed is
important. But you probably already knew that.

Best wishes,
