  undef_method :p # Remove Kernel.p here to pipe through method_missing and hit tag proxy.

  # Implements our proxying to the `@view_context` or `@view_context.tag`.
  #
  # `@view_context` proxying forwards the message and automatically appends any content, so you can do things like:
  #
  #   <% partial.body.render "form", tangible_thing: @tangible_thing %>
  #   <% partial.body.link_to @document.name, @document %>
  #   <% partial.body.t ".body" %>
  #
  # `@view_context.tag` proxy lets you build bespoke elements based on content and options provided:
  #
  #    <% partial.title "Some title content", class: "xl" %> # Write the content and options to the `title`
  #    <% partial.title.h2 ", appended" %> # => <h2 class="xl">Some title content, appended</h2>
  #
  # Note that NicePartials don't support deep merging attributes out of the box.
