+=head1 NAME
+
+Perl::Critic::Utils::PPI - Utility functions for dealing with PPI objects.
+
+
+=head1 DESCRIPTION
+
+Provides classification of L<PPI::Elements>.
+
+
+=head1 IMPORTABLE SUBS
+
+=over
+
+=item C<is_ppi_expression_or_generic_statement( $element )>
+
+Answers whether the parameter is an expression or an undifferentiated
+statement.  I.e. the parameter either is a
+L<PPI::Statement::Expression> or the class of the parameter is
+L<PPI::Statement> and not one of its subclasses other than
+C<Expression>.
+
+
+=item C<is_ppi_generic_statement( $element )>
+
+Answers whether the parameter is an undifferentiated statement, i.e.
+the parameter is a L<PPI::Statement> but not one of its subclasses.
+
+
+=item C<is_ppi_statement_subclass( $element )>
+
+Answers whether the parameter is a specialized statement, i.e. the
+parameter is a L<PPI::Statement> but the class of the parameter is not
+L<PPI::Statement>.
