RFC: #10381 [NEW]: Support for multiple results

Dear PEAR Developer Community, I'd like to ask you about your opinion about a feature request on Net_DNSBL. The issue in question is #10381. I'm in a little dilemma: Net_DNSBL is PHP4 compatible. To implementing this request, I currently see these options: - Introduce a BC break in the API - Transform the package to PHP5 and use overloading - Introduction of a new function having lots of code duplicated I don't like these options, 2 would require me to make a new package, Net_DNSBL2 (I would choose the PHP5 option then), the other is a maintenance nightmare. Maybe someone has another idea on that? Thanks in advance, Sebastian
