Without this patch the expected behavior of the count() function when
dealing with an out of bound array index and with a hash key that does
not exist is implicitly encoded in the spec examples. This is a problem
because the expected behavior is not clear for something similar to the
following example:
node default {
$ary = [ 1, 2, 3 ]
$ary_undef = $ary[100]
$hsh = { 'one' => 1 }
$hsh_undef = $hsh['dne']
$count = count(['hi', $ary_undef, $hsh_undef])
notice "Count is ${count}"
}
This patch addresses the problem by making the expected behavior
explicit in the examples.
