Re: GCC 4.0 Ada.Containers Cursor danger.

   The Lion, the Wolf, and the Fox

   A Lion, sickly, weak, and full of years,
   Desired a remedy against old age
   (_Impossible's_ a word no monarch hears
     Without directly flying [into] a rage).
   He sent for doctros - men of draughts and pills;
     From far and near, obedient to the call,
   Came makers-up of recipes and pills:
     The Fox alone declined to come at all.
   At court the Wolf malignantly referred
     To Reynard's absence, whereupon the King --
   Whose anger was aroused at what he heard --
     Decided on a rather cruel thing.
   He sent a force to smoke sly Reynaud out,
     And bring him, willy nilly. When he came,
   The Fox could scarcely entertain a doubt
     As to whose toungue had put him thus to shame.
   "I greatly fear, your Majesty," said he,
     "You think me rude; you wrong me, if you do:
   For I was on a pilgramage, you see,
     And went to offer up my vows for _you_.
   I scarcely need inform you I have met
     Expert physicians whilst I was away,
   And hope to cure you of your sickness yet,
     Which comes from coldness of the blood, they say
   You must, sire, skin a Wolf, and wrap the skin
     About you close, to get the body warmed;
   And when the heat has kindled up within
     The fires of life again, the cure's performed.
   Our friend. I'm sure, will take immense delight
     In lending you his coat; so take it, sire."
   The Lion supped on the Wolf that night,
     And made the skin a part of his attire.
   Courtiers, discretion is your safest plan:
     Malice is sure to find its source again;
   And, while you do yourself what good you can,
     Reflect that slander others is in vain.


   [La Fontaine (1621-...), "popular with everyone in
      Paris, except [Louis XIV]".
    Quoted from the Thornury's book of La Fontaine's
      fables of Aesop).]


French may need a reminding about monarchism...

Another lie.
