*I* knew.  What about other readers?  C'mon, you're the stickler for
following conventions, and isn't it a convention that Usenet posts 
should be, as much as feasible, self-contained?

(I begin to believe that the people who chide you for being overly
argumentative have a point.  But then there's the bit of flattery
later.  Hm.)

*But I don't* (have it in front of me):  If you check headers, you'll
notice that I'm using the very old trn, which as far as I know does
not provide any easy way to display two posts at the same time,
and while I do usually have saved copies of previous posts in some
other window-or-the-like ....  Well, no, no one needs to hear details
of my old-school-to-a-fault tools setup.  The point is that you
could save all readers some trouble by quoting *one line*.

Flattery will ....  something.

Good (if irritating) catch on the spelling mistake.  I know better.

The variable I named "DEBUG" is a boolean, so I don't quite get how a
convention for naming references to mutable objects applies.

(I don't really know why I brought that up, since all-caps variable
names are not idiomatic in Scala.  Just sayin', maybe.)

Okay.  How is that relevant ....
