I was writing my output to two different files. Only one of them was
set to utf-8, the other must have been some other encoding, because when
I set the encoding to utf-8 everything cleared up.

Well, at least I think that it's unicode confusion. When a store values
into a string (in an array of structs) and then compare it against
itself, it compares fine, and if I write it out at that point it writes
out fine. And validate says it's good unicode.
But later...
valid = true, len =
OK, after removing a few bugs, preliminary checks say that this works
perfectly.
Thanks again, as I never would have even considered that approach.

I've got a simple struct:

If I define a shared ulong variable, is increment an atomic operation?
E.g.
shared ulong t;

t++;
It seems as if it ought to be, but it could be split into read,
increment, store.
I started off defining a shared struct, but that seems silly, as if the
operations defined within a shared
Thanks, that's what I needed to know.
I'm still going to do it as a class, but now only the inc routine needs
to be handled specially.
(The class is so that other places where the value is used don't even
need to know that it's special. And so that instances are easy to share
between
FWIW, were I proposing a "Database Engine for D" I'd be proposing a
B+Tree that was restricted to storing explicit data (no pointers or
other indirection...including strings, you'd need to specify fixed size
arrays of char, wchar, or dchar). There would be one "type"/file, and

Esp. I'd like a standard linkage to Sqlite via D rather than C, but I'm

Additionally, I'd like fewer language changes. D is a great language

This module does not have any dependency, therefore you can just use
