`typeid` is runtime thing, you can't use it in compile-time. besides, as Ali said, `allMembers` returns tuple, which is very special thing that exists only in compile-time. > 1.

I'm wondering why members1 doesn't has a type at all. So, we don't > have a compile-time boolean? it's a tuple. actually, `(string, string, string)` is a special type. > 3. For members2, where auto is used, I would expect that the return type > of "allMembers" is used. it is. ;-) > Which would be a tuple. But again, no type for > members2. Which I find quite strange. as i said, `typeid` is runtime feature, so you can't print it with pragma. and tuples aren't exist in runtime, it's compile-time only. i think you are even more confused now. ;-) sorry.
