Yes.

A tuple expression would probably require brackets:

A comma expression result can't be used. I think it can only be 
used as an expression statement, or in the `for` *Increment* 
clause. Are there any cases where it could conflict with 
bracketed tuples? dmd accepts a comma expression with  
parentheses, but that would presumably be a 'has no effect' error 
if it was parsed as a tuple.
