I happen to know there's reflection in bidi, so example of doing this:

~ 1m 18s
❯ clj -Sdeps '{:deps {bidi/bidi {:mvn/version "2.1.6"}}}' -M -e '(set! *warn-on-reflection* true)' -r
true
user=> (require 'bidi.bidi)
Reflection warning, bidi/bidi.cljc:20:31 - call to static method decode on java.net.URLDecoder can't be resolved (argument types: java.lang.String, unknown).
nil
user=>

yes, works fine

ok, I think:

$ clj -M -e "(set! *warn-on-reflection* true)" -e '(fn [x] (.length x))'
true
Reflection warning, NO_SOURCE_PATH:1:9 - reference to field length can't be resolved.
#object[user$eval138$fn__139 0x73eb8672 "user$eval138$fn__139@73eb8672"]

will do fine then. As long as you do the set! before any other namespaces are loaded

confirmed:

$ clj -M -e "(set! *warn-on-reflection* true)" -e "(require 'asami.core)"
true
