[Issue 9256] New: A purity-related error message in case of member access
http://d.puremagic.com/issues/show_bug.cgi?id=9256

          Summary: A purity-related error message in case of member
                   access
          Product: D
          Version: D2
         Platform: x86
       OS/Version: Windows
           Status: NEW
         Keywords: diagnostic
         Severity: minor
         Priority: P2
        Component: DMD
       AssignedTo: nobody@puremagic.com

struct Foo {
   int x;
}
void main() pure {
   int y = Foo.x;
}


With DMD 2.061 gives this error message:

test.d(5): Error: pure nested function 'main' cannot access mutable data 'x'


But I think a better error message should be something like:

test.d(5): Error: need 'this' to access member x

See also:


struct Foo {
   int x;
}
void main() pure {
   int y = Foo.x.max;
}


test3.d(5): Error: pure nested function 'main' cannot access mutable data 'x'

But I think this problem is elsewhere in Bugzilla.
