Nothing wrong with passing
So, I would like to ask another question:
Is it safe to pass function reference to the caller (mostly it's the method
instantized from a class) in mod_perl development env?
Or should I avoid using this style?
Thanks.
Thanks for all your help.
Yes I have made the mistake to think {} is a code reference in perl.

Yamada-san,
The value you pass to 'run' is not a code reference, but an hash
reference, i.e. '{}'
A code reference would be: 'sub{}', so do '$obj->run( sub{ "hello
world"} );' instead.

Good afternoon,
Can you help check my problem with this?
$ cat t1.pl
use strict;
package Myclass;
sub new {
my $self = shift;
bless {},$self;
}
sub run {
my $self = shift;
my $block = shift;
&{$block};
}
1;
package main;
my $obj = Myclass->new;
$obj->run( { "hello world"} );
