I would really like to avoid such implicit conversion of handles from Persistent
to regular handles. We should make explicit the places were
this conversion is necessary and do it there. For instance when
returning values back to dart it is not necessary to convert a PersistentHandle.

This method could be
Dart_PersistentHandle customType() { return m_customType; }

Done.

 
 private:
-    WorkerCrypto();
+    DartCustomElementBinding(Dart_Handle customType);
+    Dart_PersistentHandle m_customType;
 };
