On one hand, they are allowed - at least in alpha:

    int function(int n);    // works!

On other hand, they don't serve any practical meaning -
D doesn't need them anyhow, and there is no way
to define a body once the prototype was declared:

    int function(int n) { }    // symbol conflict

So what are they for?

They're for if you really do want to create a library with a hidden
implementation of the functions. The way to do it would be make a copy of
the module, and delete the function bodies.
