-- setters: `something=` where `something` can be any valid method identifier. Their definitions require one parameter or more and no return value. If there is only one parameter, the invocation is done with `x.something = y` where `x` is the receiver and y the argument. If there is more that one parameter, the invocation is done with `x.something(y, z) = t` where `x` is the receiver, `y` the first argument, `z` the second argument and `t` the last argument.
