          Issue ID: 12639
           Summary: Struct-scoped import breaks UFCS
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: brian-schott cox.net

struct Foo
{
    Range opSlice() { return Range(); }
    static struct Range
    {
        int front() { return 10; }
        void popFront() { counter++; }
        bool empty() { return counter >= 10; }
    private:
        import std.array;
        int counter;
    }
private:
    int bar;
}

void main(string[] args)
{
    import std.stdio;
    import std.array;
    Foo foo;
    auto x = foo[].array();
    writeln(x);
}

The above example fails to compile. If you remove the "import std.array;" line
from the Range struct, this works as intended. It also works if you write "auto
x = array(foo[]);"
