Fredrick Johansson discusses [http://fredrik-j.blogspot.com/2009/03
/computing-generalized-bell-numbers.html here] his implementation of
generalized Bell numbers in mpmath. I've verified that this function is
present in the version of mpmath shipped with sage 4.3. Benchmarks show it
is faster than GAP (currently used by sage) and even mathematica. This
should be very easy to wrap.
