import std.stdio;

void main()
{
    printf("-- %s\n", __FILE__);
    printf("-- %s\n", __FUNCTION__);
    printf("-- %s\n", __PRETTY_FUNCTION__);
}

The use-case are printf statements in destructors, which unlike writef will avoid any allocations (which typically fail in dtors due to the GC being stopped).

Neither can string literals!  printf is a c-varargs function, and has no way of knowing you want the implicit conversion to const(char)*.

Solutions:
printf("-- %s\n", cast(const(char*))__FILE__);
printf("-- %.*s\n", __FILE__.length, __FILE__.ptr);

I guess that shows how spoiled I am by D's variadic templates. :)

> printf("-- %s\n", cast(const(char*))__FILE__);

Also __FILE__.ptr and __FILE__.toStringz.
