Use of := for an empty attribute list is deprecated

(D deprecated) The construction my $x := 42 currently parses correctly in perl, being equivalent to my $x : = 42 (applying an empty attribute list to $x). This useless construct is now deprecated, so := can be reclaimed as a new operator in the future.
