           Summary: tupleof an aggregate cannot be used as a template tuple
                    argument
           Product: D
           Version: 1.023
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: DMD

struct S
{
        int x;
}

class C
{
        int x;
}

union U
{
        int x;
}

alias Tuple!(S.tupleof) ST;
alias Tuple!(C.tupleof) CT;
alias Tuple!(U.tupleof) UT;

All of those instantiations give the error "Error: tuple is not a valid
template value argument".  No, but I'd suppose being tuples that they'd be
valid _tuple_ arguments, Mr. Compiler!
