           Summary: static, renamed, and selective imports aren't private
           Product: D

The spec isn't specific about what should happen in this case, but I think the
behavior is not what one would expect and is undesirable.

Basic imports are now private by default, so import std.stdio in one file A
doesn't mean writefln will be accessible in file B that imports A.  However if
you switch from  "import std.stdio" to "import io = std.stdio" then B will be
able to access io.writefln.  Similar situation with selective and static
imports.  None of them act private, and sticking an extra 'private' in front of
the import statement doesn't change anything.

Here's an example:
-------- modulefoo.d -----------
module modulefoo;

static import std.string;
import stdio = std.stdio;
import std.stdio : writef;


--------- modulebar.d ------------
module modulebar;
import modulefoo;
void main()
{
    stdio.writefln("This shouldn't work");
    std.stdio.writefln("Don't think this should either");
    stdio.writefln( std.string.format("This is odd too") );
    writef( "This doesn't seem like it should work either\n");
}

--------------
"dmd -run modulebar" generates no errors at all.
