 Currently deriving will fail miserably for at least but not limited to:
 
  * `IntoOwned`: borrowed fields like `&'a str`
- * `Borrowed`: struct/enum has more than one lifetime
- * both: arrays not supported
- * both: into_owned/borrowed types inside tuples inside vectors
+ * `Borrowed`: struct/enum has multiple lifetimes that depend on each other (explicitly or implicitly)
 
 Using with incompatible types results in not so understandable error messages. For example, given a struct:
