      That looks extremely interesting!

      However, I have a feeling (perhaps eroneously, given that I only 
started to look at it), that the support in outfmt is there only for the 
simplest variants of quaternion and octonion inputs. I was under the 
impression that a full-fledged parser was needed to clean the awfullness 
that are my current implementations (an octonion parser which might call 
a quaternion parser which might call a complex parser (or rely on the 
standard library input),...).
