'private import' and 'private alias' is not working.

[CLXX]

I found some private attributes is not working.
DMD 2.025 Windows

//aaa.d
private static import std.string;
private alias std.string.find find;
private import std.conv: to;

// main.d
import aaa;
void main( ){
  string x = "main.d";
  find( x, "." ); // should be ERROR!
  std.string.ifind( x, "." ); // sould be ERROR?
  to!( wstring )( x ); // sould be ERROR?
}

First, 'find' in 'main.d' should not be accessible because 'alias' has 'private' attribute.
Second 'std.string.ifind' should not be accessible I think, because 'std.string' in 'aaa.d' is imported privately.
Third, 'to' in 'main.d' should not be accessible I think, because 'std.conv' is imported privately.

If we want to use 'std.string.ifind' in 'main.d', we can import 'std.string' in 'main.d'.
And the same, in order to use 'to' in 'main.d', we should import 'std.conv: to'.

Less symbols we can see, more easily we can get.
