private alias for module

[Myron Alexander]

Hello.

I would like to declare an alias private to the module. As of D1.020, 
this is not the case and the specification seems to agree with the 
implementation.

By private alias, I mean (eg):

> ----- somemodule ----
> module somemodule;
> import std.string.toString;
> private alias std.string.toString str;
> ... code that uses str ...
> 
> --- main ----
> import somemodule;
> void main () {
>    str (50); // should fail
> }

Is there a way to do this?

At the moment, I understand my only options as:

1. Selective import with function rename
2. Create another module for the alias and import into "somemodule"

Problem with option 1 is that I then have to declare each function I 
use. Problem with option 2 is that I have an additional file.

If this is by design, then what is the reasoning behind forbidding 
private aliases?

Thanks ahead,

Myron Alexander.
