Problem:
(clojure.core.async/go (taoensso.telemere/log! "hello")) ; Compiles fine
(cljs.core.async/go (taoensso.telemere/log! "hello")) ; Compile fails
I could try to get to the bottom of exactly what's going on - but ultimately
IOC mechanisms like `go` are always going to be a bit fragile, especially for
heavily-optimized/unusual code.
In this case, the problem is thankfully only with Cljs - and Telemere's Cljs
performance isn't too critical - so I think we can afford to just bypass any
potential fiddling by the `go` macro by wrapping Cljs Telemere expansions in
an IIFE ((fn [] ...)).
Downside is the (small) added cost of a function construction and call.
Upside is avoiding potential issues with core.async and other similar
IOC-style systems (Electric Clojure, etc.)
