Oh yes, automatic stack is a good one! How do you think automatically managed strings might work, so that there is as little hidden code and costs as possible, but still decently ergonomic for your taste? Would you consider automatic strings good enough if restricted to (a) statically known length, (b) statically known buffer size, or is it only worth it when they can be fully dynamic?
