Thanks, I will try.

And yet cua-rect.el defined a command to enter this mode.

I don't really buy the "on a whim" argument; I think the user always
knows in advance whether the next selection will or won't be
rectangular.  So I still think a minor mode is the best solution, if
something like C-M-mouse-1 is not portable enough.
