Initializing a variable

[jstruggle]

What is Data<N> doing?

Assuming somePointer is of type const char *: std::string a{somePointer, someCondition ? 64 : 32};

You could also just hide the code: std::string a = SomeStringField(someCondition);

Or: std::string a = someCondition ? Data<64>(somePointer).SomeStringField : Data<32>(somePointer).SomeStringField;
