Note that this last step only applies if the adaptor takes no arguments.
If the adaptor takes arguments (such as <code class="computeroutput"><span class="identifier">indexed</span></code>),
then there is no need for a variable. Instead, give the tag type
a constructor that takes the arguments (and store those arguments
in the tag object). A usage of the adaptor will then involve construction
of an object of the tag type.
