 /* Support for mixin typedef.
 Consider the following example:
 
 class I<T> { }
 class J<T> { }
 class S<T> { }
 class M<T> { }
-typedef A<U, V> = Object with M<Map<U, V>> implements I<V>;
-typedef C<T, K> = S<T> with A<T, List<K>> implements J<K>;
+class A<U, V> = Object with M<Map<U, V>> implements I<V>;
+class C<T, K> = S<T> with A<T, List<K>> implements J<K>;
 
 Before the call to ApplyMixinTypedef, the VM has already synthesized 2 mixin
 application classes Object&M and S&A:
 
 Object&M<T> extends Object implements M<T> { ... members of M applied here ... }
 A<U, V> extends Object&M<Map<U, V>> implements I<V> { }
 
 S&A<T`, U, V> extends S<T`> implements A<U, V> { }
 C<T, K> extends S&A<T, T, List<K>> implements J<K> { }
