Fixes #15440 # Description Wraps ListStream stream type from `impl Iterator` to `Peekable<impl Iterator>`, this allows checking for empty streams and treating them as empty values Example: ``` # previously $ glob ? | default -e void > # empty list $ echo '' | default -e void > void #################### # now $ glob ? | default -e void > void $ echo '' | default -e void > void ``` # User-Facing Changes empty list streams will behave as `nothing` values when testing for emptiness # Tests + Formatting - Add 2 tests - clippy OK - fmt OK # After Submitting
