I kind of doubt that in this particular case the overhead of requiring
Sage is worth it, but it is possible to call arbitrary Sage functions
from C++ code by embedding a python interpreter. It has been done,
i.e. M2 has a sage package in the current svn that was developed at
Sage Days 14 by Dan Greyson with help of a couple Sage developers.
There were some small fixes needed for the Sage library that AFAIK
have not been merged into the main tree, but it should be relatively
simple to get that code in.
