Initializer List Ctor

[Julius Witte <julius.witte@xxxxxxxxxxxxxxxxxxxxx>]

In a class such as this one:

#include <initializer_list>
class A
{
public:
  A(int i, double d){}
  A(std::initializer_list<double> l){}
};

why an instantiation with curly braces as this one

int main()
{
  A a{2,2.} ;
}

shall default to the initializer list constructor?

I understand why a call like "A a{2.,2.}" would default to it,

but in my eyes it would make more sense to default

to the first constructor when the types match it exactly.
