// This file contains values used by tests and benchmarks.
// The benchmarks will test performance against other libraries
// (encoding/json, json-iterator, bson, gob, etc).
// Consequently, we only use values that will parse well in all engines,
// and only leverage features that work across multiple libraries for a truer comparison.
// For example,
// - JSON/BSON do not like maps with keys that are not strings,
// so we only use maps with string keys here.
// - _struct options are not honored by other libraries,
// so we don't use them in this file.
