I find myself using this pattern a lot, and I'm not sure of two things:
1) Is this standard operating procedure and there is a name for it?
2) Is it forward compatible, going to work in perl6?
All I'm doing is blessing a reference in the subroutine, "new" and then tying that blessed thingy to the same package.
Example, "MyPackage.pm"
package MyPackage;
use strict;
our $VERSION = 0;
use Tie::Hash;
use base qw(Tie::ExtraHash);
# OO Interface
sub new {
my $class = ref($_[0]) || $_[0];
my $self = bless {}, $class;
tie %$self, $class;
}
sub to_string { join ' ', %{$_[0]}; }
# Tie interface
sub STORE { $_[0][0]{$_[1]} = ucfirst($_[2]); }
1;
Example, "t-mypackage.pl" which uses "MyPackage.pm"
#!/usr/bin/perl -w
use strict;
use MyPackage;
my $p = MyPackage->new();
$$p{Hello} = "world";
print $p->to_string, "\n";
