[MacPerl] re-initializing associative arrays

[Peter Furmonavicius <PETER@yalevm.ycc.yale.edu>]

Hello.  I was under the impression that after

          $a{1} = "peter";
          undef @a;

$a{1} would have no value.  Apparently that isn't the case because $a{1}
is still equal to "peter".

Can someone tell me what is the most efficient way of re-initializing an
array?

Thanks in advance.  - peter
