	// !!! NOTE !!!
	// This is not meant to be a comparison to show which library is
	// universally faster. In fact, it is quite likely that faker and
	// chance have functions that perform better than the equivalents in
	// fictional. The 'seed each' benchmarks below are probably also
	// misuse of faker and chance. The intention of these benchmarks was
	// to investigate and show why seeding as a way of mapping
	// identifiers to generated values isn't viable, and why hashing is a
	// promising solution
