     \brief The QDBusPendingReply class contains the reply to an asynchronous method call.

     This class is similar in functionality to QDBusReply, but with two
     important differences:
 
     \list
       \li QDBusReply accepts exactly one return type, whereas
-         QDBusPendingReply can have from 1 to 8 types
+         QDBusPendingReply can have any number of types
       \li QDBusReply only works on already completed replies, whereas
          QDBusPendingReply allows one to wait for replies from pending
          calls
