I don't think you can have conditional extend commands like that (extend and
include are not Python commands -- they are processed by the template engine
before the Python is run). You can have conditional include commands, but
technically all of the included views will be included and then
conditionally executed.
You might be able to do an extend with a variable (set in the controller and
passed to the view in the returned dict) in place of the view name, but in
that case, you will not be able to bytecode compile the views because the
compiler needs to know the extended view at compile time, but it won't
actually be determined until run time.
