It is hard to argue for "must have", because the only thing we need is
a binary file editor :-)

However, the way I see reflection uses in my own work is not too far
from the examples discussed in the papers

     Ian Lynagh, May 2003.

Jacques Carette also has excellent discussions in connection with
Gaussian elimination.
