6755,[result_of] Inconsistent results between function references and function pointers,Michel Morin,Daniel Walker,"For function references, decltype-based `boost::result_of` uses `decltype` to determine the type. But, for function pointers, decltype-based `boost::result_of`
falls back to `boost::tr1_result_of` and does not use `decltype`. 

This inconsistency makes different results for function references and function pointers. 
On clang trunk and gcc-4.7 in a C++11 mode, for ""`typedef const int F();`"", 
* decltype-based `boost::result_of<F&()>` is `int`, but
* decltype-based `boost::result_of<F*()>` is `const int`.

To remove the inconsistency, 
decltype-based `boost::result_of` should use `decltype` for function pointers.
