I've found myself doing something like the following a lot in the past:

int i =3D 0, j;=

And, naturally, I caught myself doing this recently:

auto i =3D 0, j;

= About which the compiler complained since, AFAICT, it is explicitly disallo= wed. I'm curious to know why. It doesn't seem that much of a stretch to exp= ect that j's type would be decltype(i)...

Thanks for any insight abo= ut this!
