dwgebler f5139878f9 Check parameters on compact() and throw warning if not string or array of strings (#6921) ...

compact() is documented (https://www.php.net/manual/en/function.compact) as a variadic function accepting parameters which are strings or arrays of strings referencing defined symbols.

In actuality, passing nonsense parameters e.g. compact(true, 42) merely returns an empty array. I propose throwing a warning in these cases, to prevent silent bugs.
