Interesting, but I'm confused by the documentation.  perlfunc says

     keys HASH

         Returns a normal array consisting of all the keys of the
         named hash.

Is a "normal array" different than "array"?  pop wants an array.

Leaving aside the problem of lastness in a hash, why can't you pop 
off the array returned by keys HASH?

I sense there's something subtle but significant here that I'm not 
understanding.
