Maybe I can answer that, with my still very limited knowledge...and wait for
others to correct me ;-).

I would assume that since a function returns a value Out parameters would
also allow to change values outside the function. even if it's available in
other languages, it's usually recommended to not do so for good practice.
so to enforce it isn't all that bad a thing. :-).
