# Description
two cool things about the `where` command
- it's versatile enough to allow creating a case-insensitive version of
itself
- it does not require the explicit use of a closure

this PR adds an example showing how to filter with `where` but
case-insensitively and without an explicite closure.

# User-Facing Changes
new example to `where`:
```nushell
  Find case-insensitively files called "readme", without an explicit closure
  > ls | where ($it.name | str downcase) =~ readme
```

# Tests + Formatting
the new example test above.

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
