+C<use_hash_multivalue_in_request>
+
+In L<Catalyst::Request> the methods C<query_parameters>, C<body_parametes>
+and C<parameters> return a hashref where values might be scalar or an arrayref
+depending on the incoming data. In many cases this can be undesirable as it
+leads one to writing defensive code like the following:
+
+ my ($val) = ref($c->req->parameters->{a}) ?
+ @{$c->req->parameters->{a}} :
+ $c->req->parameters->{a};
+
+Setting this configuration item to true will make L<Catalyst> populate the
+attributes underlying these methods with an instance of L<Hash::MultiValue>
+which is used by L<Plack::Request> and others to solve this very issue. You
+may prefer this behavior to the default, if so enable this option (be warned
+if you enable it in a legacy application we are not sure if it is completely
+backwardly compatible).
