Also, how to handle foreach(i, x; w) (use index + value)?
I wanted to switch to std.container.Array but it doesn't seem to
mimic [] for some odd ball reason. I threw this class together
and it seems to work.
The only problem is that I can't do
carray.length -= 1;
I can't override `-=` because that is on the class. can I
override it for length

No such thing in D. But you can always be creative and use an

The only thing I've been able to figure is a horrible hack, where
your member functions are something like
// off in define_foos.d

The problem is the compiler has to assume you *might* be linking
to opaque .o files, so it can't provide any introspection
capabilities.
This is solved through simple inheritance constraints and
aliasing with qualification.
class X;
class subfoo;
class subbaz : subfoo;
class foo(T) if (is(T : subfoo)) X;
class baz(T) if (is(T : subbaz)) foo!T;
then when we need foo with "default",
alias foo = qualified.foo!subfoo;

canFind takes a range. Array isn't a range itself, but you can
get one by slicing it with []:
Have working code that uses []. Trying to replace with Array!
1. Can't use make in field initialization. Complains about malloc
in static context.
2. can't decrement the length. So Darr.length = Darr.length - 1;
fails
This means we can't remove the element easily. I see a removeBack

Sorry for the necromancy.
I failed to reproduce the issue for single threaded programs.
Which is good.
As far as std.concurrency is concerned I still have questions.

Someone figured out how to do it and put it in std.traits! ;-)
Example:
```

import core.thread;

writeln(typeid(a));

This prints "core.thread.Thread.Context" , which is a private
