# Description
Add `metadata access`, which allows accessing/inspecting the metadata of
a stream in a closure.
```nu
ls | metadata access {|meta|
...
}
```
- The metadata is provided as an argument to the closure, identical to
the record obtained with `metadata` command.
- `metadata access` passes its input stream into the closure as it is.
- Within the closure, both the metadata and the stream are available.
The closure may modify, collect or pass the stream as it is.
# Motivation
- Without this command, nu code can't act on metadata without losing the
stream, use cases requiring both the stream and metadata must be
implemented either as a built-in or a plugin.
- This command allows users to enhance presentation of data, similar to
`table` coloring the output of `ls`.
