Awesome explanation! I never really considered that pass by ref could cause be unsafe in terms of memory. Could someone at Epic create a summary for Const params as well?

Thanks for having clarified the point that pass-by-ref does not work exactly as in a regular programming language, and should not be used as a small optimization trick (this does not prevent copies!).
