tmuxq.MatchingSeq(values: iter.Seq[T], filter: Filter[T]) -> (iter.Seq[T], error)
```

MatchingSeq returns a lazy sequence of shallow copies for values that filter accepts, retaining source order. The filter is compiled before iteration begins, so an invalid filter is an error here rather than a sequence that yields nothing.
