> Only array parameters are not inlined when dumped.

This is true only when the XML debug container is used, not on a live container that can contain unresolved parameters in the `%my_param%` form. That was my mistake. We have to resolve to get the parameter type.

`$value = [];` was just an improvement to avoid useless parameter resolve btw.
