n().X = X;
I'm trying to alias nodes away but alias n = Z[0]; fails.
Dropping () from n().X fails also.

Typically a lot of algorithms have corner cases such as
referencing elements that end up out of bounds at the start or
end (k-c or k+c).
Is there any way to handle such things easily without having to
worry about the corners?
E.g., have it return a default value such as 0, or repeat the

Yes, just another error about something else that I don't
remember.
I have some algorithmic code that uses the same dereferencing
symbol quite often, like
.X
It's used in ranges, in predicates, in strings, etc and other
things but is used a lot. The object it acts on has several
fields and I would like to use them.

I also may have to break up the algorithm in to parts.

This works:
x[0] = X(123);
Should the syntax not extend to the case
struct Y { double q; }
struct X { Y[] a; }
X x;
auto r = x.a;
r is not a reference?!?!
When updating x.a, r is not updated ;/ [I'm not sure if it just
creates a slice or what]
Ok, fine!
auto r =
Now r is a reference, great!.
But now the semantics of using the array completely change

This avoids a double copy.
X y = {3};
works fine.
So one has to do
x[0] = y;

are you sure about that?
with a static size
cast(wstring)entry.szExeFile == Name
to!wstring(entry.szExeFile) == Name
These all fail. The strings are clearly the same. I can compare
char by char and it works. latest D 2.088. The only thing is that
szExeFile is a static wchar array... which shouldn't effect the

Is there a way too have a single D process run and be called
multiple times from the command line without too much work?
Basically any time the process is called by the command line it
will "enter" only one process... and if that process is being
debugged the entries can be debugged too.

Because the algorithm is complex(deterministic but chaotic) and
