tiny.preserves.observeRecord

1/// Builds the record `<Observe pattern observer>` for values whose domain is `AnyEmbedded`. Code2/// that asks for matches of a pattern calls it for a record with its label spelled once, in3/// `symbols`. The label is a new copy of the symbol `Observe`. An observer other than an embedded4/// value moves into a new allocation. The record then holds that observer as an embedded value that5/// compares, hashes, frees and copies it as a value. An observer that is already an embedded value6/// goes into the record unchanged. The record takes ownership of the pattern and the observer, so7/// `Value.deinit` frees the record with both. On `error.OutOfMemory` the call frees what it8/// allocated, and the caller still owns the pattern and the observer.9pub const observeRecord = any_records.observeRecord;
