C++ 11+ Type alias definition with 'using' not supported

[sophia-gh]

C++ 11+ allows for the definition of user-defined type aliases with using as a replacement for doing the same with typedef

Typical Structure for Using vs Typedef :

using alias = ExistingType; 

typedef ExistingType alias; 

using can be used in place of typedef to define aliases
Some examples of using and equivalent typedef alternatives

using Vec = vector<int>;
typedef vector<int> Vec; 

using FunctionPointer = void(*)(int, double); 
typedef void(*FunctionPointer)(int, double);

using charArray = char[10];
typedef char charArray[10]; 

using can also be used to define aliases with templated parameters, which typedef cannot do as simply
example:

template<typename T>
using Vec = std::vector<T>;
Vec<int> myIntegerVec;        

//there is no equivalent way to do this with typedef, bellow code is not legal
template<typename X>
typedef vector<X> Vec;    // this is not legal and would not work

//to accomplish this with typedef you would have to use a struct
template<typename Y> 
struct Vec{
    typedef std::vector<Y> type;
}; 

Vec<int>::type myIntegerVec; 

This manner of creating user-defined aliases with using is not currently supported by nameCollector, currently nameCollector does not collect any alias names defined in this manner and skips over them.
