=head1 NAME

Plass - Instance based OOP

=head1 INSTALL

$ git clone git://github.com/ytnobody/Plass.git $ cpanm ./Plass

=head1 SYNOPSIS

my $cat = plass meow => sub { print shift->voice." " }, look => sub { print shift->profile->name. " looking ". shift. " " }, voice => 'Meow...', profile => { name => "Kiki", age => 4 }, surface => [ 'Black', 'Talkable' ];

$cat->meow; ### say "Meow..."

$cat->look( "you" ); ### say "Kiki looking you"

my $talkcat = $cat->plass( voice => "I'm hungry...", look => sub { print shift->profile->name. " not looking ". shift. " " }, ); $talkcat->profile->name( "Jiji" );

$talkcat->meow; ### say "I'm hungry..."

$talkcat->look( "you" ); ### say "Jiji not looking you"

my $bird = plass fly => sub { print $[0]->name. ' flew to '. $[1]. " " };

$talkcat = $talkcat->mix( $bird );

$talkcat->fly( 'mountain' ); ### "Jiji flew to mountain.";

=head1 DESCRIPTION

An aim of Plass is to present environment of instance-based-OOP.

=head1 COMMANDS

Plass imports follow commands.

=head2 plass

my $instance = plass key => $anyval, key2 => $anyval2 ... ;

Cloning universal instance of Plass. And, Specified parameters to a cloned instance.

=head2 mix

my $instance = mix $plass_instance_1, $plass_instance_2, $plass_instance_3 ... ;

Mixing Plass based instances. But, non-recursive slot inheritance.

=head1 METHOD

Instance of Plass can call follow method.

=head2 plass

my $child = $parent->plass( key => $anyval, key2 => $anyval2 ... );

Cloning parent instance of Plass. And, Specified parameters ( calls "trait" ) to a child instance.

=head2 mix

my $child = $parent->mix( $plass_instance1, $plass_instance2 ... );

Cloning parent instance of Plass. And, Mixed-parameters of specified instances to a child instance.

=head2 feature

my %trait = $instance->feature;

Returns trait of instance. Following codes are equal among they.

my $child = $parent->plass;

my %trait = $parent->feature; my $child = plass %trait;

=head1 PHILOSOPHY

=head2 SIMPLIFICATION OF CODING

Plass aims destroy partition among class and object.

Specifically, class-name contained in Plass-object is nonsense.

Because Plass-object's class-name is "Plass".

To generate an instance in instance-based-OOP means make clone from an universal instance.

=head2 ABLE TO EXTEND EASY

In Plass, inherits is superseded by trait.

Trait is expressed by Hash that contains some-values and/or coderef.

=head2 USABILITY OVER SPEED

In developing Plass, please priority over usability than speed.

=head1 TODO

• performance benchmark.

• more friendly trait.
