Surely a stupid mistake on my part, but why is the first array
repeated?
import std.stdio;
void main()
{
int[]*[2] a; // a static arrray holding pointers to dynamic
arrays
static int unique = 0;
foreach(i, elem; a)
{
int[] temp = new int[](5);
foreach(ref
I think I got a handle on D's static and dynamic arrays, till I
come to std.array and see all the shiny new tools. I can
understand all the replace.. functions, but the appender function
gave me pause. The documentation says appender "Returns a new
Appender or RefAppender initialized with a

Yes, it means that the string

Static Arrays have property
.sizeof which returns the array length multiplied by the number
of bytes per array element.
Dynamic Arrays have property
.sizeof which returns the size of the dynamic array reference,
which is 8 in 32-bit builds and 16 on 64-bit builds.
Why not have dynamic

I'm genuinely curious. What is a function predictor used for?

One of my D books says: "an enum declared without any braces is
called a manifest constant." The example shows,
enum string author = "Mike Parker";
Is this equivalent to
const string author = "Mike Parker";
or
immutable string author = "Mike Parker";
I guess what I'm asking is does enum

Wouldn't starting array elements at one avoid the common
'off-by-one' logic error, it does
seem more natural to begin a count at 1.
Actually,
