Sean Doyle d2e07395b3 ActionView: Serialize Regexp into HTML attribute
When serializing a Regexp instance, encode the [Regexp#source][]. When
encoding a value into a [pattern][] attribute from ERB/Ruby, declaring
the String can be tedious. For example, one might attempt to encode
`\w+` as `"\\\w+"`, but once serialized to the browser, that is not
equivalent to the `"\w+"` HTML attribute.

Instead, enable declaring Regexp and Regexp literals as attributes, and
encoding them as their source String.

= Action View

Action View is a framework for handling view template lookup and rendering, and provides
view helpers that assist when building HTML forms, Atom feeds and more.
Template formats that Action View handles are ERB (embedded Ruby, typically
used to inline short Ruby snippets inside HTML), and XML Builder.

You can read more about Action View in the {Action View Overview}[https://edgeguides.rubyonrails.org/action_view_overview.html] guide.
