+=head1 NAME
+
+Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument C<substr> instead of writing C<substr($foo, 2, 6) = $bar>.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+Conway discourages the use of C<substr()> as an lvalue, instead
+recommending that the 4-argument version of C<substr()> be used instead.
+
+  substr($something, 1, 2) = $newvalue;     # not ok
+  substr($something, 1, 2, $newvalue);      # ok
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
