Re: The top-level cv-qualifiers on the template-parameter are ignored when determining its type

I had some code that was failing to compile which amounts to something
like what's shown below. After some digging around, I came across
paragraph 14.1 note 5, which states :

"The top-level cv-qualifiers on the template-parameter are ignored
when determining its type."

Can someone comment on the reasoning behind this?

#include <iostream>
#include <typeinfo>

class Bar {};

template<class T>
void Func(T t)
{
    std::cout << typeid(T).name() << "\n";
}

template<class T>
void Func(const T& t)
{
    std::cout << "const ref : " << typeid(T).name() << "\n";
}

int main()
{
    Bar bar;
    const Bar& constBar = bar;

    Func(constBar);

    return 0;
}

gcc gives :

temp.cpp: In function 'int main()':
temp.cpp:24: error: call of overloaded 'Func(const Bar&)' is ambiguous
temp.cpp:7: note: candidates are: void Func(T) [with T = Bar]
temp.cpp:13: note: void Func(const T&) [with T = Bar]
