Is there anything wrong with passing a hash reference like this:

#!/usr/bin/perl

$fruit{'Apple'} = "Red";
$fruit{'Orange'} = "Orange";
$fruit{'Grape'} = "Purple";
$fruit{'Lemon'} = "Yellow";
$fruit{'Lime'} = "Green";

$myHashref=\%fruit;
print "Hash reference to send = $myHashref\n";
print "Print local hash\n\n";
foreach $key (sort keys %fruit) {
     print $key, '=', $fruit{$key}, "\n";
}
print "\nLeaving Main\n\n";
&mysubrtn($myHashref);



sub mysubrtn() {
  local *myref = shift ;
  print "In my Subrtn\n";
  print "Print hash via reference\n\n";
  foreach $key (sort keys %myref )  {
     print $key, '=', $myref{$key}, "\n";
  }
}

I believe this is called the typeglob approach. The original example code is below.
This doesn't seem to be as straight forward to me. Is this just my lack of understanding? Opinions?

[root@dubya perl]# cat fruit2.pl
#!/usr/bin/perl

$fruit{'Apple'} = "Red";
$fruit{'Orange'} = "Orange";
$fruit{'Grape'} = "Purple";
$fruit{'Lemon'} = "Yellow";
$fruit{'Lime'} = "Green";

$myHashref=\%fruit;
print "Hash reference to send = $myHashref\n";
print "Print local hash\n\n";
foreach $key (sort keys %fruit) {
     print $key, '=', $fruit{$key}, "\n";
}
print "\nLeaving Main\n\n";
&mysubrtn($myHashref);



sub mysubrtn() {
  $myref = shift ;
  print "In my Subrtn\n";
  print "Print hash via reference\n\n";
  foreach $key (sort keys %$myref )  {
     print $key, '=', ${ $myref }{$key}, "\n";
  }
}
