I'm curious what you think the problems are that unbounded indices causes? Unsigned overflow is well defined in C++, so I don't see the problem here. AFAIK, the only issue would be with requiring power of 2 sizes.

Yeah. Just requires power of 2 sizes and handling of write_idx < read_idx.

AFAIK write_idx < read_idx case is handled automatically by doing the unsigned subtraction.

Power of 2 requirement stands, though.
