Yeah. The only times that something is going to accept shared is when it was specifically designed to work as shared (which most code isn't), or if it's templated and the template happens to work with shared. Regular functions just aren't going to work with shared without casting away shared, because that would usually mean either templating everything or duplicating functions all over the place. - Jonathan M Davis
