because %in is a tied hash (tied by ReadParse), nothing is ever stored
inside that hash, the tied methods use the object which is tied to it to
get/set data.  so, there is no 'bucket usage', same as:
% perl -e 'print scalar %hash'
0

scalar(%hash) gives zero

My script has these lines in it,

  my %in; CGI::ReadParse(\%in);
  print scalar(%in);
  print %in;

Then I run it under shell,

  bash$ ./myscript.pl foo=1 bar=2

It gives me 

  0foo1bar2

Can anyone explain why the "0" but not the bucket usage?
