I think D112361 <https://reviews.llvm.org/D112361> is a step in the right direction. You can do even better and make it represent a contiguous (not necessarily fixed-size) buffer with type-erased reallocation/flush. Then it can be used to write to contiguous containers like vector and string which is a common case directly avoiding copies. This is basically what {fmt} does.
