... no. structs are for storing structured data. They may be rather large,
they may aggregate smaller structs. In my entire career as a programmer, I
can count the number of times I've wanted to pass a struct by value on
perhaps one hand.

I _rarely_ need pointers

If you need pointers at all, and you want to stick with D's modern
pointers-shouldn't-appear-in-day-to-day-code idiom, then you need ref.

That's not a solution, it's not even a work around, it's a totally
different operation. I may not want to, or can't, pass my data by value.
