Does the D language set in stone that the first element of an

Wouldn't starting array elements at one avoid the common
'off-by-one' logic error, it does
seem more natural to begin a count at 1.
Actually, maybe even better to allow array definitions of form
int foo[x:y];
(y >= x) creating integer variables foo[x], foo[x+1],...,foo[y].
This experiment has already been run. Perl used to support a $[
variable to set the array base. After experience with the
confusion and problems that causes, it was finally deprecated and
effectively removed from the language. See the end paragraphs of
http://perldoc.perl.org/perlvar.html and also
http://search.cpan.org/~wolfsage/perl/ext/arybase/arybase.pm for
more info.
