Rails 3 & nested layouts

Rails
1

Has anyone seen a solution for nested layouts that works with Rails 3?
I’ve tried several previously documented patterns, including

but keep getting
no block given

thanks

Same problem.
I tried this example from Rails Guide (it’s been copied to Rails 3
version on http://guides.rails.info/) on a blank project both with
ruby 1.9.1 and 1.8.7. Always the LocalJumpError - no block given.
Actually I’m surprised I can’t find any published workaround. That’s
not some subtle obscure little bug. Nobody’s using nested layouts?
I posted this question on stackoverflow. Still no suggestions.
