When trying to compile I get:

stdio.std in at c:\dmd\bin\..\src\phobos\c\stdio.d(69)

That's not the only combination of imports that will give the error.  I 
seem to get the error with all sorts of variations when stream is imported.

Thanks for any help.

Use "stream.stdin" to reference it.  This is why I want private imports.

 Use "stream.stdin" to reference it.  This is why I want private imports.

I was just playing with importing "string" and "math" and got into a 
similar situation with atof().

It seems to me that this may be more of a problem with the libraries and 
error messages rather than the language itself (?).  I would think that 
normally your core libraries should not conflict with each other. (eg. 
why is there an atof in both string _and_ math? Why is there a stdin in 
both stream and c.stdio? Shouldn't one import from the other?).

With alias you can "fix" normal conflicts... I just wasn't expecting the 
standard library to conflict with itself.

The error messages seem to make sense but are less clear than what you 
would get out of most C++ compilers when a namespace conflict occurs. 
GCC will output something like:
   test.cpp: In function `int main()':
   test.cpp:16: use of `i' is ambiguous
   test.cpp:8:   first declared as `int Foo::i' here
   test.cpp:3:   also declared as `int Bar::i' here

Which shows exactly where you were trying to use the conflicting item 
and why this is an error in the first place.
