=head1 NAME

Specio::Constraint::AnyDoes - A class for constraints which require a class name or an object that does a specific role

=head1 VERSION

version 0.47

=head1 SYNOPSIS

    my $type = Specio::Constraint::AnyDoes->new(...);
    print $type->role;

=head1 DESCRIPTION

This is a specialized type constraint class for types which require a class
name or an object that does a specific role.

=head1 API

This class provides all of the same methods as L<Specio::Constraint::Simple>,
with a few differences:

=head2 Specio::Constraint::AnyDoes->new( ... )

The C<parent> parameter is ignored if it passed, as it is always set to the
C<Defined> type.

The C<inline_generator> and C<constraint> parameters are also ignored. This
class provides its own default inline generator subroutine reference.

This class overrides the C<message_generator> default if none is provided.

Finally, this class requires an additional parameter, C<role>. This must be a
single role name.

=head2 $any_isa->role

Returns the role name passed to the constructor.

=head1 ROLES

This class does the L<Specio::Constraint::Role::DoesType>,
L<Specio::Constraint::Role::Interface>, L<Specio::Role::Inlinable>, and
L<MooseX::Clone> roles.

=head1 SUPPORT

Bugs may be submitted at L<https://github.com/houseabsolute/Specio/issues>.

I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.
