When trying to compile some test code with the latest (svn) versions of dmd2 and phobos, i get the error: ..\src\phobos\std\format.d(1139): Error: shadowing declaration std.format.formatValue!(LockingTextWriter,PolicyItemGroup[],immut able(char)).formatValue.f is deprecated where line 1139 is auto f = FormatSpec!Char(f.nested); and one of the functions parameters is also called f.
This seems to be fixed now.
