Recently I have stumbled across user defined literals, especially the templated variadic char array kinds:
template<char... chars>
constexpr size_t operator""_size(){
return sizeof...(chars);
}
//Later
constexpr size_t size = "this is text"_size;
Is there any way to do this with a normal constexpr function?
Something like this:
template<char... chars>
constexpr size_t size(){
return sizeof...(chars);
}
//Later
constexpr size_t size = size("this is text");
This would allow multiple parameters and regular syntax.
So is there any way to do do the templated variadic char array as a parameter trick to normal functions (or some way to achieve a similar effect)?
