"The problem with Rhino's AutoCAD style Trim command is that it's inconsistent with the regular "noun, verb" type selection sequence. Having some commands work in reverse selection order from others is one of the things that tends to make Rhino more difficult for beginners to learn."

I don't know about anyone else, but this statement makes me excited. When you write "[...]"noun,verb" type selection.
