# 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.
