Neither: the empty program compiles and runs, outputting nothing.
Since its empty output matches its empty source file, it
technically fits the definition of the quine :)

Array was designed before the @nogc attribute was created, so it wasn't

allocates GC memory for exception throwing in some cases. These can and
