I just noticed your reference to (set! *print-meta* true) which does
actually show the meta in macroexpand (at least in my example):
(set! *print-meta* true)
(macroexpand `(do
(schema.core/defn
~(with-meta 'create {:always-validate true}) [])))
=> (do (schema.core/defn ^{:always-validate true} create []))
Secondly, I need to work a bit more to call myself a beginner with
macros, so take everything I say with a good dose of salt ;).
