           Summary: Protection attributes of mixin instances are applied in
                    a wrong scope.
           Product: D
           Version: 0.173
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid, spec
          Severity: normal
          Priority: P4
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: brunodomedeiros+bugz@gmail.com


Protection attributes of mixin instances are applied in a wrong scope. The following illustrates it:
---- baz.d ----
module baz;

template Baz() {
    private void privfunc(){ }
}
---- ----
import baz;

class Foo {
    mixin Baz!();

    void testfunc() {
        privfunc(); // Error: .privfunc is private
    }
}
---- ----
For reference the spec states (http://www.digitalmars.com/d/mixin.html):
"Unlike a template instantiation, a template mixin's body is evaluated within
the scope where the mixin appears, not where the template declaration is
defined. It is analogous to cutting and pasting the body of the template into
the location of the mixin."
If the current compiler behavior is the intended behavior then fix the spec.

This is what I was talking about in the "Is a template like copy-paste" thread. Actually I was referring to copy-paste made by mixins.

Are the specs wrong?
