I didn't know you could do this. It's just a placeholder when you don't care about that arg. Very functional.

Is that an equivalent for null or does it something else? --- Met vriendelijke groeten - Best regards - Salutations Ivan Porto Carrero GSM: +32.486.787.582 Blog: http://flanders.co.nz<http://flanders.co.nz/> Twitter: http://twitter.com/casualjim _______________________________________________ Ironruby-core mailing list Ironruby-core@rubyforge.org<mailto:Ironruby-core@rubyforge.org> http://rubyforge.org/mailman/listinfo/ironruby-core
