Instead of this, I'm considering an approach where my functions instead return 
a data structure containing a description of the side-effects to be performed 
(e.g. "insert these rows into this table", "send this email", ...), and having 
a single non-pure function that does all the side-effectful work described by 
the structure.

See https://github.com/seancorfield/engine which I built to investigate exactly 
that approach. We haven’t started using it at work (World Singles) but that is 
the plan so I’d be interested in getting more feedback on it. I have not yet 
released it to Clojars.
