I see no problem with the array_{merge|intersect|diff|flip|etc.} functions
taking non-array parameters, since they all _return_ the resulting array. As
long as they don't promote a non-array variable passed as a parameter into an
array as a side-effect, I don't see the problem. I'd say revert the change and
keep it as it was.
