Good point!  (I guess there's _always_ "more than one way to do it" in
programming languages. ;-)

I guess from that perspective, I would have expected "real" and "imag"
to be "member" functions: x.real(), x.imag().  (Or am I still thinking
too much like C++?)

It's an affectionate term (sortta ;-) for someone who lives in the state
of Iowa, USA.  (See http://www.slanguage.com/minneapolis.html.)

If "Iowegian" were a vanity plate, it would be pronounced something
like:

	IOWEJN

(Rhymes with "Norwegian".)

I grew up in Missouri, and now I live in Kansas, but I lived in Iowa for
a long time: it was really nice.
