Overview

This is used for the block variable given to form_for. Typically, an erb template looks as so:

<% form_for :foo do |f|
  <%= f.text_field :bar %>
<% end %>

form_for adds the form tag to the input stream, and assumes that later the user will append the <input> tag to the input stream himself (in erb, this is done with the <%= %> tags).

We could do the following in Markaby:

form_for :foo do |f|
  text f.text_field(:bar)
end

But this is ugly. This is prettier:

form_for :foo do |f|
  f.text_field :bar
end
