I really should use parenthesis less as obviously people don't read the 
content between them.  (Not just you, I'm afraid! ;^)  If it weren't a 
useful feature (for/empty) I'm unsure as to why so many template 
engines implement it even though in most of them you _can_ utilize a 
sentinel value; at least, in the ones that allow embedded Python code.

Alas, the BDFL has spoken, however.  (Getting shot down was not 
unexpected despite the occasional +1000. ;)
