Just looked at the option to use `xavp_params_implode` followed by `xavp_params_explode` no luck with that because `xavp_params_explode` will fail to parse emtpy params.
Example: `$xavp(x[0]=>y) = "";`
Will fail to parse because `y=;` is not supported.
I am looking at existing solution before considering code modification ...
