Ah, but why?  :-)  Besides, the use of 1, i, j, k for quaternion units
is inconsistent with using 1, j (not 1, i) for complex units.

Why not just go all the way and support full geometric algebras of
arbitrary dimensionality?

The answer is, of course, because programmers don't generally need such
functionality built into the language.

(There is a geometric algebra module for Python, by the way.)
