When I need to hack around an 'auto' bug, I sometimes factor out the
return type to a template:

template IotaRet(B, E, S = size_t)
{
    alias Take!(Sequence!("a.field[0] + n * a.field[1]",
                Tuple!(CommonType!(B, E), S))) IotaRet;
}

IotaRet!(B, E, S) iota(B, E, S)(B begin, E end, S step) {}

IotaRet!(B, E) iota(B, E)(B begin, E end) {}
