The problem is that ERB#result(binding) takes a binding so I need the 
binding. The templates used in this case relies on Rails rules (member 
variables in a controller are available in the ERB template) and I need 
to create a binding containing everything from the controller scope (and 
then add the new needed stuff from the model).

What about passing a block from outer scope and call it from inner scope 
and pass in a Hash with variables from the inner scope, then loop over 
the variables and add those as instance members (using instance_eval), 
create the binding (inside the block) and then invoke ERB.result. Could 
that work?
