.SH "NAME"
Package::New \- Simple base package from which to inherit
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\&  package My::Package;
\&  use base qw{Package::New}; #provides new and initialize
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The Package::New object provides a consistent constructor for objects.
.PP
I find that I always need these two methods in every package that I build.  I plan to use this package as the base for all of my \s-1CPAN\s0 packages.
.SH "RECOMMENDATIONS"
.IX Header "RECOMMENDATIONS"
.SS "Sane defaults"
.IX Subsection "Sane defaults"
I recommend that you have sane default for all of your object properties.  I recommend using code like this.
.PP
.Vb 6
\&  sub myproperty {
\&    my $self=shift;
\&    $self\->{"myproperty"}=shift if @_;
\&    $self\->{"myproperty"}="Default Value" unless defined $self\->{"myproperty"};
\&    return $self\->{"myproperty"};
\&  }
.Ve
.SS "use strict and warnings"
.IX Subsection "use strict and warnings"
I recommend to always use strict, warnings and our version.
.PP
.Vb 5
\&  package My::Package;
\&  use base qw{Package::New};
\&  use strict;
\&  use warnings;
\&  our $VERSION=\*(Aq0.01\*(Aq;

.SS "Lazy Load where you can"

I recommend Lazy Loading where you can.
.PP
.Vb 5

\&    my $self=shift;
\&    $self\->load unless $self\->loaded;

.Vb 1
\&  my $obj = Package::New\->new(key=>$value, ...);
.Ve
.SS "initialize"
.IX Subsection "initialize"
You can override this method in your package if you need to do something after construction.  But, lazy loading may be a better option.
