Can't assign string literal to boxed std::string vector

Question

This is a simplified version of my type system:

#include 
#include 

template
class Box {
public:
    Box(const T&a         


        

Answer 1

You could use a helper function that creates the corresponding type:

template 
Box make_boxed(const R& value){
    return Box(value);
}

it may seem like additional complication that one has to specify the T, on the other hand you can use auto for the returned type. Complete example:

#include 

template
class Box {
public:
    Box(const T& value) : _value(value) {};
private:
    T _value;
    /* ... */
};

typedef Box String;

int main(int argc, char* argv[]) {
    auto a = make_boxed("asd");
}
