I noticed just making many threads cause an error.
Are there any limit for the number of threads?
import std.concurrency;

void fun() { Thread.sleep(5000.msecs); }
void testThread() {
foreach(i; 0..2000) {

Hi, do you think it's possible to implemented something like Lua Tables
(a hashed heterogeneous associative array) in D?
I know that Lua is dynamic and interpreted, hence it's a lot simpler to
do than with a compiled language but I'm wondering if we could express
such a generic data-structure

So I've been mostly just toying around with D as it seems like it
will end up being a strong language for game development both now
and even moreso in the future. That being said, I'm perplexed by
using this code and not receiving the result I would imagine.
