[Bug c++/33255] New: A warning for "unused" typedefs?

[pcarlini at suse dot de]

Just a wild idea, motivated by libstdc++/33084: in that case we had a function
with this body:

      typedef _BinClos<_Name, _Constant, _ValArray, _Tp, _Tp> _Closure;
      typedef typename __fun<_Name, _Tp>::result_type _Rt;
      return _Expr<_Closure, _Tp>(_Closure(__t, __v));

where the fact that _Rt was completely pointless clearly hinted to a bug, a
typo _Tp -> _Rt in the last line. Would it make sense to add an option to the
front-end to warn in such cases?
