So on the topic of subscriptions. Our schema has a dataloader (superlifter) that is started in an interceptors :enter, and cleaned up in an interceptors :leave . Now, in the lacinia.pedestals subscription attaching, I can pass an interceptor chain, but it seems that the chain is executed in both directions prior to me even calling source-stream . So I was wondering whether there is a way to do ‘around’ actions like this for single invocations of source-stream. I mean, like ‘data loader start’ -> ‘source stream calling’ -> ‘nested selection resolving (using the dataloader)’ -> ‘dataloader cleanup’.
