I went digging through the archives, made more interesting as elementtree was
imported into the standard library.
AFAICT, the FutureWarning for __bool__ (or __nonzero__ in py2) appeared circa

It's easier to justify a change in behaviour if the warning is emitted. With no

Because error() mentions standard error and exit() does not, I assumed exit()
did not use stderr, but it does.

The reason for getting rid of "unset" is the confusion of "state", i.e

Please extend pdb's continue to support an optional argument, identical to
break.
When debugging I frequently want to quickly run to a certain line number then
break. Rather than break / continue / clear (or tbreak / continue), it would be
handy to type
