Clojure private const vars?

New to clojure and i'm wondering.. can i define a var as both ^:private and ^:const?

So for instance, would it make sense to do the following:

(def ^:private ^:const everything 42)

Yes, on any sufficiently modern Clojure version.

long ago the metadata keywords didn't "roll up" but that was fixed years ago.

the ^:keyword reader-macro is just a syntactic shorthand for ^{:keyword true}

user> (def ^:private ^:const everything 42)
#'user/everything
user> (meta #'everything)
{:const true, :private true, :line 241457, :column 7, :file "*cider-repl api*", :name everything, :ns #namespace[user]}

is the same as:

user> (def ^{:private true :const true} everything 42)
#'user/everything
user> (meta #'everything)
{:private true, :const true, :line 241816, :column 7, :file "*cider-repl api*", :name everything, :ns #namespace[user]}
