# Description
Use `record!` macro instead of defining two separate `vec!` for `cols`
and `vals` when appropriate.
This visually aligns the key with the value.
Further more you don't have to deal with the construction of `Record {
cols, vals }` so we can hide the implementation details in the future.
## State
Not covering all possible commands yet, also some tests/examples are
better expressed by creating cols and vals separately.
# User/Developer-Facing Changes
The examples and tests should read more natural. No relevant functional
change
# Bycatch
Where I noticed it I replaced usage of `Value` constructors with
`Span::test_data()` or `Span::unknown()` to the `Value::test_...`
constructors. This should make things more readable and also simplify
changes to the `Span` system in the future.

nu-cmd-extra
the extra commands are not part of the Nushell binary
The commands in this crate are the extra commands of Nushell. They do not get built for the release and it is the responsibility of the developer to build these commands if they want to use them.
These commands are not going to part of the 1.0 Api; meaning that there is no guarantee longer term that these commands will be around into the future. Of course since they are part of the source tree one could always incorporate them into their own custom release.
How to build the commands in this crate
Step 1 is to read the installation notes for Nushell which is located in our Nushell book.
Once Rust is installed you can then build Nushell with the following command.
cargo build --features=extra
Your Nushell binary which just got built is called nu and will be located here.
