But "As of release 5 of Perl, assignment to $[ is treated as a com-
piler directive, and cannot influence the behavior of any other
file.". So it only influences the current file, onwards from where
it is set.
$ perl -Mstrict -MData::Dumper -wle'
my @x; $[ = -1;
$x[0] = "abc"; $[ = 1;
$x[1] = "cde";
print Dumper [EMAIL PROTECTED]
'
$VAR1 = [
'cde',
'abc'
];
