Now that you have an eval tag, maybe you don't need this, but I think
Django already had a simpler solution to your problem:
Context:
buttonDecidedAtRunTime: 'button4.html'
thisPage: "/some/path"
blah.html:
<p>{% include buttonDecidedAtRunTime %}</p>
The argument to the include tag doesn't need to be a literal string, it
can be a value from the context. This has the added advantage that the
common "{% include " in each of your button choices is factored out and
appears only once, in blah.html.
