\item Is SAGE {\dred ``impossible''}???:

I've never understood how you can think something that
sits on top of python can beat some custom code like
magma. How does SAGE multiply two numbers? Does it use
python to do it? I was trying to explain SAGE and failed
miserably.

\item SAGE can be very fast, since it is partly written in {\dred
    Pyrex}, which is a Python-like language that is converted to C and
  compiled: {\tt\small
    http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/} My plan
  is that all of SAGE's basic arithmetic types will be
  (re-)written this way in the next few months.

\item Martin Albrecht and I have had to {\dred modify Pyrex}.
