> The Go SDK supports all the integer types of the language, but does not support floats.
> My plan for coding is to use the same technique the gob package uses, which results in
a compact encoding for simple values.
> [https://golang.org/src/encoding/gob/encode.go?#L210|https://golang.org/src/encoding/gob/encode.go#L210] with
rationale explained in https://golang.org/pkg/encoding/gob/#hdr-Encoding_Details
> The resulting uint is then encoded using the existing coders in coderx.
