A task can only run when it’s being awaited by another task https://vorpus.org/blog/notes-on-structured-concurrency-or-go-statement-considered-harmful/Sketching an API Task greet() { cout co_return co_await resolveOn(name, "1.1.1.1"); }); co_return visit(identity{}, v); }Structured concurrency Tasks naturally form a "call tree" • coroutines • leaf awaitables (sleeping, I/O, cancel()? No longer a simple allOf()Dynamic allOf() We have created a fundamental primitive of structured concurrency • nursery in Python trio • task group in Python asyncio • task scope in Rust • coroutine

Structured types can be nested to unlimited levels. Arrays, sequences, tuples, objects, and sets belong to the structured types. Array and sequence types Arrays are a homogeneous type, meaning that each element in the array has the same type. Arrays always

For example, if we want to check the property name before binding, we can write something like this: class ResourceLoader(id: way.
