Bugging is probably only way to get anything done during the semester ;)

So <length(names)> is the answer, right?  It will yield a string with  
0, 1 or n for any attribute.  Iterable ones get walked and counted  
(slow but general).  Also we want <m:{key | <key>, <m.(key)>}> for  
walking maps, right?

How can we insert a newline when length is greater than 80?  Technically

<if(length(names)>80)><\n><endif>

doesn't break the rules but then I must do flow analysis to prevent  
you from testing attribute values.
