[Follow-up]RE: Printing with arrow notation

[RArul]

In my response, shown below, if I replace 
        $rhash=shift; # My approach
with
        $rhash=@_;        # Your Approach

then nothing will be printed. The reason is that the results are interpreted
in a scalar notation when you adopt the latter approach. Therefore, never
attempt to do an assignment as shown. If at all you still wanted to do that,
you could have given a,
        $rhash = @_[0];
that would have forced it to be in scalar context, though I do not think it
is a good idea to use array-slices either to the left or right of the
assignment. You can be at least pretty lax when having something like
@array[0] on the right side of the assignment, but never on the left hand
side though.

Thanks,
Rex

%hash =('key1'=>'value1','key2'=> 'value2');
 
PrintHash(\%hash);
sub PrintHash{
  $rhash = shift;
  for(keys %{$rhash}){
        print "$_ => $rhash->{$_}\n";
  }
}

would work.

I am passing a hash as a reference to a subroutine and want to print its 
values using arrow notation. Such as..
%hash ("value1", "value2", etc..);
PrintHash(\%hash);
    sub PrintHash
{
  $rhash = @_;
  What would work here for print using arrow notation?
}
Thanks
