hello.

what is the best way to throw exception from initializer list? for example:

class C {
  T0 t0; // can be either valid or invalid, but does not throw directly
  T1 t1; // heavy object, do not construct if t0 is invalid,  by throwing before
  C(int n)
    : t0(n), // throw exception if t0(n) is not valid
      t1() {}
};

I thought maybe making wrapper, e.g. t0(throw_if_invalid(n)).

What is the practice to handle such cases?

Thanks
