Wrap it in a thread and parking take from it

(a/go (a/<! (a/thread (slurp ""))))

Exactly

Don’t think you need the go and the <! Since a/thread returns a channel with the value already

I suppose the assumption was that there is more code inside the go block. I am now indeed just doing a/thread . Guessing there is virtually no difference between that and future .. ?

Future returns a deref-able thing, thread returns channel
