Sometimes, you just want to read a byte (or write one). Doing so with rawRead
or rawWrite is awkward, because first you have to declare a buffer, then use
the buffer, then convert to the place where you actually want to use it. A
3-statement process is pretty inconvenient.

However, what if rawRead/rawWrite could have overloads that deal with one item:

```d
T rawRead(T)() if (!isArray!T) {...}
void rawWrite(T)(in T item) if (!isArray!T) {...}
```

Or stdio could provide wrappers that do this, they don't have to be overloads.

Just some way to do in one line what it currently takes 3 lines to do.
