Everything should be made as simple as possible, but not simpler.

I'm going from memory here, but I think that Walter views syntax in the
form 

  ( identifier )

as bad form or at least a waste, and as it also looks like a C style cast,
he decided to outlaw it.

However, it's not very consistent because this next line compiles ...

   a = cast(int)( ((b))*x );

So the upshot is if you ever find yourself needing

  ( identifier )

code it as 

  (( identifier ))

and it'll work.
