     So, you get to see

	int value = things[i].x;

... and then you answer "yes" or "no?"

     Trust me, Martin: An IDE will do this *much* more easily and *much*
more accurately than what you've described, because the IDE knows what
type `things[i]' is, even if the declaration is four hundred lines away
from the point of use.

     There certainly was a time when Java IDE's were rather pathetically
awful.  I started using NetBeans at version 3 (my then employer's
choice), and it wasn't until version 5 that it became worth the trouble.
But it has in fact become worth the trouble, and an impression of its
uselessness that you might have formed some years ago may not still be
accurate.  (I've had only the briefest exposure to Eclipse and none at
all to other Java IDE's, but I'd imagine they, too, have progressed.)

     "Horses for courses," you said, and that's fine.  But I'd encourage
you to take a fresh look at the stable; the horses there are no longer
helpless foals.
