  Ubuntu, lein 1.7.1 - lein repl

In lein 1.7.1 (and CCW) the form (def ^{:type :anything} mydef 1) throws "ClassCastException clojure.lang.Var cannot be cast to clojure.lang.IObj clojure.core/with-meta (core.clj:211)".
This seems to be due to setting the :type metadata. With other metadata keys it works well.

If it is intended to forbid setting the :type metadata, then there should be an appropriate error message instead of the ClassCastException

In lein2 repl which is using "REPL-y 0.1.0-beta8" the exception does not occur.
