Similarly, these do not set the local variable.

~~~
$ echo ' josh' | ruby -ne '/(?<initial>\w)/ !~ $_ or puts initial'
$ echo ' josh' | ruby -ne '$_[/(?<initial>\w)/] and puts initial'

Broken when using `~`:

~~~
$ echo ' josh' | ruby -ne '~/(?<initial>\w)/ and puts initial'
-e:1:in `<main>': undefined local variable or method `initial' for main:Object (NameError)

Working when using `=~ $_`:

~~~
$ echo ' josh' | ruby -ne '/(?<initial>\w)/ =~ $_ and puts initial'
j
