Gpseq is a parallelism library for Vala and GObject.

```vala

using Gpseq;

void main () {

    string[] array = {"dog", "cat", "pig", "boar", "bear"};

    Seq.of_array(array)

        .parallel()

        .filter(g => g.length == 3)

        .map(g => g.up())

        .foreach(g => print("%s\n", g))

        .wait();

}

// (possibly unordered) output:

// DOG

// CAT

// PIG

```

```vala

using Gpseq;

void main () {

    Channel chan = Channel.bounded(0);

    run( () => chan.send("ping").ok() );

    print("%s\n", chan.recv().value);

}

// output:

// ping

```
