with that knowledge, would also be possible to define new types
(not aliases, but new encapsulated types) representing things
such as Graph, Ring, Topology, surreal number, etc?
I dont find this in your book, would you consider either adding

All these Result types are simply structs. Struct

I think at least a short mention is in order. :)
There are two reasons why they don't appear in the book (yet):
1) They are not a proper language feature, rather a ha
Ali Çehreli:
When you eagerly need an actual array of the elements, call
std.array.array on Result:
import std.array;
import std.algorithm;
void main()
{
auto input = "hello world";
auto splittedWords = input.splitter(' ').array;
Or just use the eager split() function.

What is the purpose of this 'Result' type? To serve as a generic
range? Because, it seems to only cause problems. For example,
you cannot assign or cast the result type into a range, even when
assert(c.equal(e));
typeof(c).stringof.writeln;
}
```
The program prints:

It's a Voldemort type, representing a range that iterates over its
elements lazily.

The point is to be a range over the original input, evaluated
lazily. Using this building block, you can create an array, or

Yes this is a lazy input range. Use `.array` to yield directly as
a concrete value,
then you can append using `~=`.

It's not a property, it's a Phobos function from std.array.
