This is expected as all string literals should be zero-terminated D strings. So the following works as expected:

```
void main()
{
   import core.stdc.stdio;
   printf(__FUNCTION__.ptr);
}
```

The interesting bit is why __FILE__ and __MODULE__ can be passed directly to printf.

No, this is not expected. I can use printf with a string literal, and it works, even if it's via an enum, or some const folding. The compiler implicitly can cast a string literal to a const(char*), otherwise using C functions with string literals would be painful.

For example:

printf("hello" ~ "\n"); // ok
enum x = "hello";
printf(x); // ok
enum y = __FUNCTION__;
printf(y); // nope
enum z = ctfeFunction();
printf(z); // nope

I think all of these should work, they are all string literals, and should be 0 terminated.
