This pattern is extremely repetitive and can be abstracted:
```rs
let args = args.evaluate_once(registry)?;
let tag = args.name_tag();
let input = args.input;
let stream = async_stream! {
let values: Vec<Value> = input.values.collect().await;
let mut concat_string = String::new();
let mut latest_tag: Option<Tag> = None;
for value in values {
latest_tag = Some(value_tag.clone());
let value_span = value.tag.span;
match &value.value {
UntaggedValue::Primitive(Primitive::String(s)) => {
concat_string.push_str(&s);
concat_string.push_str("\n");
}
_ => yield Err(ShellError::labeled_error_with_secondary(
"Expected a string from pipeline",
"requires string input",
name_span,
"value originates from here",
value_span,
)),
}
}
```
Mandatory and Optional in parse_command
trace_remaining?
select_fields and select_fields take unnecessary Tag
Value#value should be Value#untagged
Unify dictionary building, probably around a macro
