Concurrency and parallelism may be emphasized well with this
simple example:
foreach(i, ref elem; task_pool.parallel(logs)) {
elem = log(i + 1.0);
}
Keeping the (straight forward) serial semantics, we write
parallelizable code.
Another good example, that demonstrates concurrency model
borrowed from Erlang is:
while (cont) {
receive(
(int msg) { writeln("int received: ", msg) },
(string msg) {
cont = (msg == "stop") ? false : true;
}
);
}
The 'send' part you can easily add by yourself.
Both examples emphasize requiring little and giving much.
