Mongo script gotchas

• no console.log, use print instead
• no Object.entries, Object.values use Object.keys
• Map, Set are not spec-compliant, Set values are stringified, Map are not iterable, don't use them
• for (const foo of [1]) {} is also broken, it needs a let/var instead of const (warning: let might not be block-scoped as per spec, they probably just replace it by var)
• Use doc._id + '' to get the objectId as hex string, don't rely on template strings also, they seem to incorrectly invoke doc._id.toString() which returns 'ObjectId(hexstring)'
• Outdated RegExp, not supporting look-behinds
