My question is why it doesn't works and if there's a workaround
For the same reason `ref` wouldn't work in this place: It doesn't accept rvalues.
A workaround might be to create a global variable that is initialized to the value you want, and use this as the default value. But this probably isn't what you look for, because you're most likely going to overwrite it, so the next time the function gets called, it will have a different value.
