The proposed definition 'myArgument' is still not correct:
\begin{axiom}
myArgument(-1+%i)
\end{axiom}
but should be $\frac{3\pi}{4}$. We cannot get around the ordering of the ring
involved... Of course, as soon as variables are involved, we cannot know
anymore in which quadrant we are. So in this case we really should return
'argument' unevaluated. This would probably involve making it an operator. A
different possibility would be to introduce a new two argument operator 'atan'
paralleling the one in 'Float' and 'DoubleFloat'.
