That just means that if you do:
my $x = {};
my $y = bless $x, "THING";
$y and $x will both be the same thing, a {} blessed into "Thing"
Its just more convenien

Can you share the code?
I believe the bless is returning the reference to self, which is captured
in a variable with name self and that variable is returned from new method.
Does that explains it?
Thanks
Kiran.

HI all
I am using object oriented perl and saw return self as well as bless being used
According to docs bless returns the reference to self. Why should we use both
statements in the new method

This is how you make objects in Perl. The bless function adds some
meta data to the variable that is blessed telling it that it is now of
class $class. You will usually

It depends on how much you know. ;-)
Basically it takes a reference to a perl type and tags it as an object,
so that in addition to being a reference to a type, it now has special
properties: primarily that it can have subroutines

Hi all.
I need to "cast" a scalar reference (SCALAR0x) into a reference to
an object that I can use. (in other words, bless it).
How can I do it?

Peter and Jenda,
Thank you both for your information and pointers, I appreciated
them.
I actually ended up doing something slightly different; I wanted
to make method calls use identical syntax, whether they were going to the

I think this should be OK.

hello friends,
i have a doubt in the concept of blessing.
package Animal;
sub named {
my $class = shift;
my $name = shift;
bless \$name, $class;
}
sub eat{
my $class = shift;
$class = ref($class) || $class;
my $food = shift;
print "$class eats $food\n&qu
Thanks for all your replies, the backticks work!
