=head1 NAME

Valiant::Proxy::Array - Wrap a hashref in a result object for validation.

=head1 SYNOPSIS

    TBD

=head1 DESCRIPTION

Allows you to run validations against a HashRef.

You probably won't use this directly (although you can) since we have L<Valiant::Class> to
encapsulate the most common patterns for this need.

=head1 SEE ALSO

This does the interface defined by L<Valiant::Result> so see the docs on that.
 
Also: L<Valiant>, L<Valiant::Validator>, L<Valiant::Validator::Each>.
