I asked this over on stackoverflow.com to see what people using other
languages have to say, as well as the D community. The reason I ask is
to see if memory allocation can be allowed in functions marked nothrow.

In a program Out of Memory is recoverable, for example your program can use
several caches, buffers, and it can use data already present on disk too, or
data that can be moved on disk now.
A good program when finds an out of memory situation can clear its caches,
delete not essential data

It can be. For example, if you want to allocate a gigantic buffer to see if
you can load a file, you may catch for failure, and display an appropriate

Since resource contention for memory allocations seems to be a big issue in D,
at least for me, and memory allocation is usually pretty fast, would it make
sense to make the lock used for GC.malloc a spinlock? Since memory allocation
takes very little time relative to a full timeslice, there is

I have a problem:
What's wrong about this code?
Code:
import std.stdio;
int main() {
writefln(%f, add(100, 786, 56.0));
return 0;
}
double add(double delegate()[] dgs...) {
double result = 0;
foreach(double delegate() dg; dgs) {
result += dg;

Just change that line to result += dg();. A delegate is like a
function; you call it to get the value.
Oh thank you.
I see. That's a stupid mistake of mine :D

Reply to Tomas,
The problem is that B has two vtables that implement the interface I.
However, in A.addChild, i.parent get's the first one (introduced by
A), and in main, it gets the second one (J , which derived from I).
The identity check then fails because the pointers aren't the same,
