I'd say if we were to add a keyword, same would be on the list of choices, I 
can't think of a common usage for it.

But you can't deny that in general using a commonly used symbol as a keyword 
might be a bad idea.

For example 'get' or 'next'.

So yes, when adding a keyword, one should be wary of how it affects commonly 
used keywords, and yes, 'same' is a good choice in that regard ;)

For example, when porting Tango to D2, I had to change about 5 or so 
singleton members (and their uses) named 'shared' since it is now a keyword.
