I think C++ should use notation similar to designated initializers (that C++ adapted from C99) for names arguments, i.e. rectangle->set(.x = 10, .y = 20, .width

I think C++ should use notation similar to designated initializers (that C++ adapted from C99) for names arguments, i.e. rectangle->set(.x = 10, .y = 20, .width = 20, .height = 20) Otherwise, it would be very confusing that two different syntax are used for similar purpose.
