Eeeks, Sorry Shlomi, I can't help thinking my German lessons have been

You're welcome, Andrew! Just note that my name is spelled "Shlomi" - not
"Schlomi". See:

You can also call me "Rindolf":

Thank you very much Schlomi - I stand corrected!
Frank, another way of putting what Schlomi has illustrated is that:
%{$self->{'DATA'}} = ( foo => 'bar' );
means "change the contents of the hash which $self->{'DATA'} refers to",
while
$self->{'DATA'} = { foo => 'bar' };
means "change $self->{'

No - they are not exactly the same. See below:

The first line works on the physical reference $self->{'DATA'} and empties it.
The second one assigns a new empty refe
Hi Frank
I found the first one rather obscure, but they are equivalent. To prove
this, Data::Dumper is my friend:
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
{
my $self;
print "selfish self \n";
%{$self->{'DATA'}} = ( foo => 'bar' );
print Dumper $self;
}
{
my $self;

The hashref of key "DATA" equals an empty list. The trailing bracket is the
end of the else block. $self is also probably blessed (an object).
ref($self->{
Could someone please explain the difference between:
%{$self->{'DATA'}} = () }
and
$self->{'DATA'} = {}
I was told that they are equivalent, but they're not. One works and
the other doesn't, so they must be different. Here's the context:
