Yes. The values to test for are true, false (but not undef), and undef.
In practice, such a flag can get set through a perl boolean, so "0" is
not the only possible false-but-defined value. I'd hate to have to do
$matched = /PATTERN/ || 0;
just to get around that.
The meaning of the test is "did I set this to false?", so it must be set
(= defined), and false.
