Another, much less flexible, option - the one used by the Linux kernel developers, apparently - is to have a blanket license on the Code Catacombs area that covers any code posted therein, and any poster has to click 'Accept' before the code is posted. Simpler, but reads 7 on the Policy Evil-o-Meter. :-)

Let us hope that that never happens, or there will be much gnashing of teeth, and fewer submissions as a result. Perl is about freedom, and taking away someone's freedom to license their code as they wish is a Bad Idea (tm). If I wanted to not have license freedom, I'd work for $EL_CAMINO_BIGNUM_COMPANY. :)
