DoWithData?

[craigpastro]

Hi, me again!

Any thoughts to adding a generic DoWithData[T](ctx context.Context, b Backoff, f RetryFunc[T]) (T, error) {...} function similar to https://pkg.go.dev/github.com/cenkalti/backoff/v4#RetryWithData? Obviously, I could use that, but the API here seems more intuitive to me.

Also happy to try a PR if this is something you are interested in.

Thanks!
