That the anonymous array consists of values identical to their indices is
probably not enlightening you.
Consider the following:
perl -e 'use Data::Dumper; @c = (qw / one two / )[0]; print Dumper ([EMAIL
PROTECTED]) '
$VAR1 = [
'one'
];
perl -e 'use Data::Dumper; @c = (qw / one two / )[1]; print Dumper ([EMAIL
PROTECTED]) '
$VAR1 = [
'two'
];
# there is no 2nd element in the source array -- only [0] and [1] are defined.
perl -e 'use Data::Dumper; @c = (qw / one two / )[2]; print Dumper ([EMAIL
PROTECTED]) '
$VAR1 = [];
#
# a slice of the first two elements in the source array
#
perl -e 'use Data::Dumper; @c = (qw / one two / )[0,1]; print Dumper ([EMAIL
PROTECTED]) '
$VAR1 = [
'one',
'two'
];
