That would be totally brilliant, since it means that one wouldn't have  
to know the default value in order to skip an argument.

We looked into this a couple of months ago and the info I got from the  
engineer that dug into the code was that it would be relatively  
complicated to implement in the engine (we were considering a keyword  
back then, sth like foo(default, true);).

But if it can be done... I'm all for it. It's definitely useful.
