I need a way to know (using traits or other compile time constructs)
all the types derived from a given type.
Is it possible in D?
Is it possible to get a list of all the user-defined classes? I could
use that to filter out the classes that I

Good Evening from Berlin!
Have been reading the chapter about concurrency by Andrei. Nice.
I have some questions, of varying quality, I'm sure.
Let's say that we have some sort of structure of rather complex data. To give

In the following example the import statement was mixed into the class

import std.traits;
class Foo
{
import std.string;
static assert(isNumeric!int);
}
foo.d(6):

Hello,
Is there an equivalent of 'in' for (non-associative) arrays? Cannot find any
'contains' function.
(Wouldn't it be nice to have in work for all arrays? What is the reason why it
only works with AAs?)

Is there another way than defining the parser (== list of patterns) at

I only knew the answer because I had almost exactly the same bug a week

Oh, but they are not the same. enum declares a constant, whereas static
declares a variable. A static global is still mutable.
Thank you for your answers,

putting it in Foo simply puts it in a namespace.
So my (wrong) idea of immutable applied to a struct was that every thing in
such namespace becomes immutable (I think this is a bit more intuitive).

I agree, except I more and more think that scope classes were a

wrapping a class inside a struct would give it RAII semantics.

You'll want to choose either the input or the output stream, otherwise
you might get eaten by a deadlock.
