Sidenote, sort also not works with static arrays.
gorithm.iteration.sum(R, E)(R r, E seed) if
(isInputRange!R && !isInfinite!R && is(typeof(seed = seed +
r.front)))
So a dynamic array works just fine. In fact, if I uncomment
the line in question the program compiles and outputs the
correct value (for a2). Why does "sum" not work

I tried to simplify your example a little bit:
import std.stdio;
import std.range;
import std.algorithm;
auto myFilter(R1, R2)(R1 a, R2 b)
{
return a.filter!(c => c==b.front);
}
struct A

`choose`'s parameters aren't lazy. So the second argument is
evaluated even when `previous is null`. That means
`intervalRange` is called on a null `previous`. And that fails,
of course, because `intervalRange` can't access `starts`

I'm having some trouble with a "Program exited with code

The problem stems from some incompatibility between the Phobos

returns a range. The code

You fell for the C# syntax like me...
According to Ahli. You have to use the old C way of doing it with
readf.

The solution is that readln() returns a string that also contains
the newline
this can be solved by easily stripping the

Oh, right, I totally forgot about that. Thank you for reminding
me.
And yes, I was not planning on doing that. I just have a local
fixed-size array that I wanted to

ubyte a;
a = cast(ubyte)c + cast(ubyte)c;
}
dmd v2.065 complains about:

As far as I can tell, adding two values of the same type should
the result of ubyte + ubyte is int I believe.
Try;

From
toUTF16 can take a char[], wchar[] or dchar[].
But toUTF16z can only take a char[]. Why?
I'm storing some text as dchar[] internally and have to pass it to WinAPI
Unicode functions which expect null-terminated UTF16 strings. But toUTF16z only
works with char[] for some reason.
I guess this should do it:
const(wchar)* toUTF16z(in dchar[] s)
{
return (toUTF16(s) ~ \000).ptr;
}
