I can't speak for why this particular notation was used, obviously,
but the '<<' operation is used similarly in other places as well, not
just appending to an array. I look at it as basically a generic
append; in the case of the class's eigenclass, you're appending
something to it (perhaps creating the eigenclass in the first place).
