Yes, this is how it's done.
Not quite with function3, because it takes one unnamed runtime

Of course we have to and the struct that I wrote is illegal

Perhaps you are trying to read as a type for which a conversion
from string to it is @system? Not sure if that's possible.

Hah of course. I assumed the name would give it some special

This looks like what I was looking for. At least I think I
understand what's going on here. The other two suggestions are
beyond my scope yet, but I'll come back, when I improved on my D
skills. Thanks for your replies.

Uh ? It's safe
Just tried
import std.stdio;
void main(string[] args) @safe
{
File f;
ubyte[] z;
z = f.rawRead(z);
}
And it compiles (DMD 2.
