Either that, or using macros or simply inline code.  While

	a.real = b.real * c.real - b.imag * c.imag,
		a.imag = b.real * c.imag + b.imag * c.real;

is much uglier than

	A = B * C,

since it is all generated automatically I doubt you will hear the
computer complain. :-)

What I do not understand is why FORTRAN programmers never complain
about the lack of built-in quaternions.
