Everything else in reference

Mutant Capability Reference This is the canonical, category-grouped catalog of every Mutant builtin. There are currently 409 registered builtins across 33 capability categories. Graph Database The db builtins embed a property graph database in the mutant runtime for modeling entities and the relationships between them: people and documents in a knowledge graph, or processes, files, and… Secure Networking & Traffic Interception Mutant ships a networking toolkit in its standard library so that tools such as TLS clients/servers and mitmproxy-style interception proxies can be written entirely in Mutant source. Structured Data: JSON, Encoding, Compression & Conversion Every fallible builtin here follows the language convention of returning (result, err); destructure with let value, err = ... and check err before touching value.
