#define dbg(...) std::cout << __LINE__ << #__VA_ARGS__ << " = "
<< print_func(__VA_ARGS__) << std::endl;
```
You probably just want
void dbg(Args...)(Args args, size_t

nothrow only applies to Exception and its children. Error is a

Error means you have a programming error and cannot be caught and

How does that pertain to an array?
C arrays work as pointers to the first element and D can use that
