Place your attributes on the right hand side of the function, not the
left side.
Use the left side for attributes/type qualifiers that go on the return type.
```d
bool[7] stagesToProcess = false;
bool shouldDoInStages(int index) @nogc nothrow @safe
{
return stagesToProcess[index];
}

It doesn't return anything.
Its return type is void.
See the argument list where it lists the types of the arguments:
``template writeln is not callable using argument types !()(string, void)``
Which aligns with the arguments you passed to ``wr

Why make func() Nullable? It just wants to give you an int,

I wrote a "count newlines" based on mapped files. It used about
twice the CPU of the version which just read 1 meg at a time. I
thought something was amiss (needless slice indirection or
something), so I wrote the code in C. It had the same CPU usage
as the D version. So...mapped files, not

Technically, no implicit conversion is
Interesting. Thank you to both of you.
