Hm, I agree that the type could be deduced. I could nevertheless have sworn that this should be invalid: .......................... template int cmp1(T a, T b); int (*cmp)(int, int) = cmp1; ........................... But it compiles in fact. I had no idea a template name could be implicitly instantiated in this context. Thanks for educating me! Best W.
