NAME
    MooseX::Declare - Declarative syntax for Moose

SYNOPSIS
        use MooseX::Declare;

        class BankAccount {
            has 'balance' => ( isa => 'Num', is => 'rw', default => 0 );

            method deposit (Num $amount) {
                $self->balance( $self->balance + $amount );
            }

            method withdraw (Num $amount) {
                my $current_balance = $self->balance();
                ( $current_balance >= $amount )
                    || confess "Account overdrawn";
                $self->balance( $current_balance - $amount );
            }
        }

        class CheckingAccount extends BankAccount {
            has 'overdraft_account' => ( isa => 'BankAccount', is => 'rw' );

            before withdraw (Num $amount) {
                my $overdraft_amount = $amount - $self->balance();
                if ( $self->overdraft_account && $overdraft_amount > 0 ) {
                    $self->overdraft_account->withdraw($overdraft_amount);
                    $self->deposit($overdraft_amount);
                }
            }
        }

DESCRIPTION
    This module provides syntactic sugar for Moose, the postmodern object
    system for Perl 5. When used, it sets up the "class" and "role"
    keywords.

KEYWORDS
  class
        class Foo { ... }

        my $anon_class = class { ... };

    Declares a new class. The class can be either named or anonymous,
    depending on whether or not a classname is given. Within the class
    definition Moose and MooseX::Method::Signatures are set up automatically
    in addition to the other keywords described in this document. At the end
    of the definition the class will be made immutable. namespace::clean is
    injected to clean up Moose for you.

    It's possible to specify options for classes:

    extends
            class Foo extends Bar { ... }

        Sets a superclass for the class being declared.

    with
            class Foo with Role { ... }

        Applies a role to the class being declared.

    is mutable
            class Foo is mutable { ... }

        Causes the class not to be made immutable after its definition.

  role
        role Foo { ... }

        my $anon_role = role { ... };

    Declares a new role. The role can be either named or anonymous,
    depending on wheter or not a name is given. Within the role definition
    Moose::Role and MooseX::Method::Signatures are set up automatically in
    addition to the other keywords described in this document. Again,
    namespace::clean is injected to clean up Moose::Role and for you.

    It's possible to specify options for roles:

    with
            role Foo with Bar { ... }

        Applies a role to the role being declared.

  before / after / around / override / augment
        before   foo ($x, $y, $z) { ... }
        after    bar ($x, $y, $z) { ... }
        around   baz ($x, $y, $z) { ... }
        override moo ($x, $y, $z) { ... }
        augment  kuh ($x, $y, $z) { ... }

    Add a method modifier. Those work like documented in Moose, except for
    the slightly nicer syntax and the method signatures, which work like
    documented in MooseX::Method::Signatures.

    For the "around" modifier an additional argument called $orig is
    automatically set up as the invocant for the method.
