Hi all,
I was looking at D as the next language to use in my hobby
projects, but the
"conservative GC" part in the language spec
(http://dlang.org/spec/garbage.html) looks a bit concerning. I'm
wondering what
are the implications of the fact that current GC is a Boehm-style
conservative

Can you live with
Container!int c = Container!int.create();
because D supports that and can force the issue with `@disable
this();` which causes compilation to fail any
is it possible to intercept the STDOUT or STDERR and capture the
output into a variable ?
some pseudocode to explain what I mean
string[] output_buffer;
stdout.capture_to(output_buffer);
writeln("test 1"); # not printed
writeln("test 2"); # not printed
stdout.release(output_buffer);
C#'s "Dispose" pattern comes to mind here.
You don't leak memory, you just leak file handles and graphics
resources instead when you forget to explicitly call Dispose().

It is indeed possible to initialize

Yes, the situation is different from C++ but it's always possible to
call a function (which constructor is one) to make the object.
It is indeed possible to initialize immutable
Unless I'm missing something, it seems that neither of these are
actually possible.
Consider an object which needs internal state to function.
The obvious answer is to create it in the constructor:
struct Foo(T)
{
T* payload;
this() { payload =

Adding a .dup works around the problem.
OK. Hmm, but the real use case was a bit more complicated, more
like:
-
int n = 10;
foreach (i; 0..n)

Options:
- The class can maintain state
- You can start the fiber with a delegate;
int local;
double state;

That's because the fiber is not in a callable state. (You can
check with search.state.) Here is one where the fiber function
