=head1 SYNOPSIS

  ; .replyrc
  [LoadClass]

=head1 DESCRIPTION

If executing a line of code fails due to a method not being defined on a
package, this plugin will load the corresponding module and then try executing
the line again. This simplifies common cases like running C<< DateTime->now >>
at the prompt before loading L<DateTime> - this plugin will cause DateTime to
be loaded implicitly.
