It's stuff like this that's just useless and gives a bad direction to the whole discussion. There's hardly anything wrong with auto x = t1[2] or auto gr = t1[1], but once the bikeshed is up for painting, the rainbow won't suffice.
I was just explaining why _ can't be used as wildcard (unless you also make _ a not valid variable name), it wasn't meant to be an example of why wildcards are useful in the first place.
