I totally agree to drop this behavior and stick to the documented behavior.

I don't think however that adding a new keyword for this purpose is a good 
idea. Quoting and evaluating are two different things that shouldn't be 
mixed, for example you may want to evaluate and still quote your expression 
result, or you may need to evaluate twice your result.

If someone feels that the evaluation functionnality is needed, I suggest to 
give acces to it in python expressions, for example:

   <div tal:content="structure python:taleval(expression)" />

and you can choose to quote or not the result using the structure keyword.
