tmuxq.FirstSeq(values: iter.Seq[T], predicate: func(*T) bool) -> (T, bool)
```

FirstSeq returns a shallow copy of the first source-ordered sequence value accepted by predicate and stops pulling later values. If no value matches, it returns the zero value of T and false. With an infinite input that never matches, FirstSeq does not return.
