I'm inclined to believe there's some benefit to explicitly using 
immutable as Walter has written about it more than once, and it's 
in D's own documentation.
While I'm sure the compiler can infer immutability, it probably 
becomes more difficult as the lifetime of the objects become more 
complicated... but I'm in no position to make a statement about 
it, maybe Walter or Andrei could chime in.
