+* New lint `empty-let` for replacing (let [] ...) with (do ...)
+* New lint `duplicate-table-keys` for detecting duplicate keys (eg. `{:a 1 :a 2}`)
+* New lint `mismatched-argument-count` for ensuring function calls have the right argument count
+    * Disabled by default because it gives false positives when your arglist doesn't follow fennel's naming conventions
