          Issue ID: 17063
           Summary: Nested function template cannot be accessed
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: jens.mueller at sociomantic.com

The following code does not compile with dmd v2.072.2. It gives

test.d(3): Error: function test.__unittestL6_1.bar!cast(ubyte)0u.bar is a
nested function and cannot be accessed from test.foo!(bar).foo

void foo(alias fun)()
{
    fun();
}

unittest
{
    // needs to be a template to cause the compilation to fail
    void bar(ubyte a = 0)()
    {
    }

    // workaround
    alias blub = bar!0;
    foo!blub();

    foo!bar();
}

The problem seems to be the function template. When the function template is
explicitly initialized it works.
