How to print custom objects?

Question

This references says printable<%> should be implemented, and that it seems to be a wrapper around prop:custom-write.

But the docs for prop:custom-write say it's deprecated in favor of gen:custom-write.

See: [_gen:custom-write for Racket classes_](https://stackoverflow.com/questions/54844089/gencustom-write-for-racket-classes). Don't worry too much about prop:custom-write being deprecated: it's just not necessary for "users" to use because `gen:custom-write` and `printable<%>` both exist as a replacement interface — Alex Knauth, Jul 02 '19 at 15:29

If you are using the Racket class and object system, then implement printable<%>. If you are using structs, then use gen:custom-write.
