 * [#709](https://github.com/clojure-emacs/clojure-mode/pull/709): Fix `clojure-get-indent-spec` and `put-clojure-indent` converting legacy indent specs, like those of `letfn`, `reify` or `extend-protocol`, to the wrong modern rules.
 * [#709](https://github.com/clojure-emacs/clojure-mode/pull/709): Fix indenting with a modern indent spec that has an `:inner` rule with a position but no `:block` rule, like `((:inner 1 0))`, which signaled an error.
+* [#711](https://github.com/clojure-emacs/clojure-mode/pull/711): Fix the indentation of `letfn` functions, and of other forms an `:inner` rule with an index applies to, when a `#_` form comes before them, as the discarded form and its `#_` counted as two arguments.
