Well they are implemented in code, but used by view

The problem is the "40".  What if you need to do truncate but not in  
the middle of an HTML tag?  I have been thinking about size of  
strings as you have seen on the list.  I wonder if a truncate  
operator would be useful in general.  I can easily make a renderer  
that truncates, but there is no way to pass it an argument...that is  
specifically disallowed in general as it would be too much like code,  
but perhaps a special operator would satisfy everybody :)
