Using undefined number of arguments in mixins

Question

I currently have -webkit specific attributes in my Less CSS sheet, I am trying to update them with mixins to add -moz attributes, like

Answer 1

You could try

.transition(@1) {
    -webkit-transition: @1;
    -moz-transition: @1;
}
.transition-2(@1, @2) {
    .transition(@1); // this includes all the stuff from transition(@1)
    color:red; // additional stuff
}

As for your actual question, I dont believe that LESS itself has any sort of "rest" style arguments passing.
