So am I.
Booleans have to be int. A boolean may have any "numeric" value, but if
implicitly cast to a numeric type, it should return 1 or 0.
D IS A PRACTICAL PROGRAMMING LANGUAGE.
Forcing booleans to be 1/0 all the way is just academic, purist,
impractical bigotry. About as smart as having the bit type.
(Besides, if booleans, as some say here, are _only_ abstract concepts,
then we might as well decide to have 0 mean true and 1 mean false. Heh,
there's only one truth but millions of lies! But we live in a world with
other people. And computers.)
Now, specifying 0 to mean false and everything else to mean not-false,
we go along with the hardware, the computer industry, half a century of
programming PRACTICE, and make life less difficult for anybody with a
professional programming background before moving to D.
Anybody who wants a tight-ass boolean, can define one for themselves.
