Yes, but "any number...of arguments" != "variable numbers of arguments". Quite right, but I shouldn't have said "any". "any ... type" != "does not support ... union arguments". Although it's a basically a moot point anyway - I can't recall any instance where I've seen a union passed directly by value, i.e. foo (union_var). It's generally passed either by resolving it to one of its specific types, i.e. foo(union_var.int_val), or by passing a pointer, i.e. foo(&union_var). This email sent to site_archiver@lists.apple.com
