Apropos fun. Consider this:

package main

import (
    "C"
    "fmt"
    "os"
)

func main() {}

//export Yaph
func Yaph() {
    fmt.Println("Every day I get in the queue")
    fmt.Println("To get on the bus that takes me to you")
}

//export Acme
func Acme() {
    go func() {
        fmt.Println("I guess i'm a closure")
        fmt.Println (os.Getpid())
    }()
}

Compile it:

go build -o yaph.so -buildmode=c-shared

Run it:

#!/usr/bin/env perl

use strict;
use warnings;
use FFI::Platypus;

use feature qw ( say );

say qq($0 $$);

my $ffi = FFI::Platypus->new( api => 1 );

$ffi->lib('./yaph.so');

$ffi->attach(Yaph => []);

$ffi->attach(Acme => []);

Yaph();

Acme() for 1..3;

END  {
    say qq(Too much, Magic Bus!) for 1 .. 3;
}

__END__

Result:

./run.pl 12350
Every day I get in the queue
To get on the bus that takes me to you
I guess i'm a closure

And i guess that there are many TMTOWTDI's.

Thanks for any hint and advice.
