what
| is the advantage of the D way?

from the doc:
The reasons to have them are:
  a.. The function declaration makes it clear what the inputs and outputs to the
function are.
  b.. It eliminates the need for IDL as a separate language.
  c.. It provides more information to the compiler, enabling more error checking
and possibly better code generation.
  d.. It (perhaps?) eliminates the need for reference (&) declarations.
I can't actually find a definition of what in/inout/out do. I guess it's clear
from the
names and the examples but it would be nice to have more details in there.

afaik, in provides a copy of the variable, inout a reference to a 
variable, and out a reference to a variable that has been set to its 
default value.

But I May Be Wrong. :-o
