Also, real-world numbers tend to swarm around powers of 10 and, in computers, powers of 2. It might make sense to encode those in a special way. E.g. <pow2-pref

Also, real-world numbers tend to swarm around powers of 10 and, in computers, powers of 2. It might make sense to encode those in a special way. E.g. <pow2-prefix><var-len-power><0/1 - to subtract one> and <pow10-prefix><var-len-power><0/1 - to subtract one>. E.g. assuming 10 prefix reserved for pow2 and 11 for pow10, 255 would be encoded as 10_1000_1, 65535 would be 10_10000_1, 65536 would be 10_10000_0, and 10000 would be 11_11_0.
