I must admit I don't understand quite what this is supposed to
do, but it looks to me like it can get shorter.  Why the 2 instances
of "load", if you're trying to make it short?  Does this not do
the same thing:

  {{exch dup exec} dup exec}

yields the same (or equivalent) value of what?  How about a sample
invocation, just so dim-wits like me can catch on?

Thanks,
