+## Feature Support Refresher
+
+### Some features work exactly as expected
+
+<ul>
+<li>Classes and functions</li>
+<li>Member properties (Readonly or Mutable)</li>
+<li>Higher-order functions (lambda as Parameter or Return)</li>
+<li>Collections with custom types</li>
+<li>Unit and Nothing</li>
+<li>Abstract classes</li>
+<li>Open classes</li>
+<li>Interfaces</li>
+<li>Extension function over usual class</li>
+<li>Extension properties over usual class</li>
+</ul>
+
+### Some features work with a small workaround
+
+<ul>
+<li>Top-level functions</li>
+<li>Top-level properties (Read-only or Mutable)</li>
+<li>Exceptions</li>
+<li>Function overloads</li>
+<li>Functions with default arguments</li>
+<li>Functions expecting lambda with receiver</li>
+<li>Functions with receivers</li>
+<li>Basic types</li>
+<li>Optional basic types</li>
+<li>Collections with basic types</li>
+<li>Mutable / immutable collections</li>
+<li>Enum classes</li>
+<li>Inner classes</li>
+<li>Sealed classes</li>
+<li>Objects</li>

+<li>Contravariant generics</li>
+<li>Covariant generics</li>
+<li>Star projections</li>
+</ul>
+
