Is there not a way to achive somthing very similar already within c+
+0x? I am thinking of using the
return type of the variadic template form of the literal operator
(obtained via decltype) as template argument.

template <char...> class A { };
template <char...Values> unsigned A<Values> operator"B"();

template <typename AT>
class CharSeq
{...};

typedef CharSeq<decltype("catch"B)> CatchKeyword;

not sure whether this works... any comments welcome.
