That's a valid position to have in general.  I can also imagine cases in
which you would choose other things.  It's a spectrum.

Prefab structs are not modular.  It is the same as in a module where
`sprout' is bound.  Reading #s(sprout bean #f 17) may create an RTD if
needed, but it does not create any bindings.

As the documentation clearly indicates :), prefab structs are indeed
compared by name, though in a combination with other characteristics
(number of fields, and more characteristics for racket).
