Here’s what I see reproducing this in the REPL - this main project doesn't use
core.async (but does use a very small AOT'd library). I'm going to try to cut
this down to see if I can repro outside our main project (worldsingles.cache is
a thin wrapper over core.cache and core.memoize - moving that exact same code
to a fresh project, without any other dependencies, works so it's something in
combination with our other dependencies):
user=> (require 'worldsingles.cache)
nil
user=> (defn foo[n] (+ 13 n))
#'user/foo
user=> (worldsingles.cache/memo foo "site")
