=head1 NAME

MooX::Failover - Instantiate Moo classes with failover

=head1 VERSION

v0.3.4

=head1 SYNOPSIS

  # In your class:

  package MyClass;

  use Moo;

  use MooX::Failover;

  has 'attr' => ( ... );

  # after attributes are defined:

  failover_to 'OtherClass';

  ...

  # When using the class

  my $obj = MyClass->new( %args );

  # If %args contains missing or invalid values or new otherwise

  # fails, then $obj will be of type "OtherClass".

=head1 DESCRIPTION

This module provides constructor failover for L classes.

For example, if a class cannot be instantiated because of invalid arguments

(perhaps from an untrusted source), then instead it returns the

failover class (passing the same arguments to that class).

It is roughly equivalent to using

  my $obj = eval { MyClass->new(%args) //

     OtherClass->new( %args, error => $@ );

This allows for cleaner design, by not forcing you to duplicate type

checking for constructor parameters.

See the module documentation for L for more information.

=head1 SEE ALSO

This was originally a L port of L.  The

interface was redesigned significantly, to be more efficient.
