The statement that reads everything belonging to any of these parents.
One statement for every parent rather than one for each, with each key its

long it is.
Read the signature
- The text after the name is the type checked by Pudu.
- Read arrows from left to right: inputs come first, and the final type is returned.
- & borrows a value for this call instead of moving or copying it.
- Names inside [ ] are type arguments, such as the item type held by a collection.
- Option holds Some(value) or None when no value is available.
- Result makes success and recoverable failure part of the function's type.
