I've just added experimental support to "go routines" to Perlito's Go backend:
$ perl mp6.pl -Bgo -e ' go sub { say 123; say "aaa" }; go sub { say 456; say "bbb" }; say "here"; say "now"; '
here123456
nowaaabbb
Go "Channels" are not supported yet.
Changelog for version 4.0:
- Go backend bootstrap.
The Go backend was updated to the latest Go language spec.
- Perl5 backend optimized; 30% faster
- More library functions, added to all backends
- New 'Eval.pm' module - implements a MiniPerl6 interpreter in MiniPerl6.
This should add some debugging capabilities later on.
MiniPerl6 (mp6) is a subset of Perl 6, which was designed as a light bootstrapping language.
Changelog for version 3.0:
- Go language backend; using Go: http://golang.org/
- Java-class backend; using Rhino: http://www.mozilla.org/rhino
- util/mp6.pl - compiler command line script written in MiniPerl6
I've been working on the "Go language" backend for Perlito miniperl6 for about 2 weeks now.
Yesterday I implemented functions and namespaces, and today I've got methods working. With some more work, Perlito should bootstrap in Go.
There is no command line script yet - I'm using this ugly line for tests (this compiles and runs the method tests):
Press the "Execute" button!
"Perlito" MiniPerl6 is an implementation of a small subset of Perl6. There is no error handling, and the web interface I wrote is very simple.
The compiler implements simple classes, grammars with 'token' only, variable binding with ':=' (no assignment), arrays, hashes, strings, integers.
I've downloaded V8 (the javascript compiler). I was planning to try it out as a MiniPerl6 backend, but I started to play with the parser instead:

MiniPerl6 (mp6) was designed as a light bootstrapping language. The initial bootstrap used v6.pm and was then self-hosted in Perl 5.
MiniPerl6 is now self-hosted in SBCL Lisp. You can modify the source code and recompile without Perl 5.
MiniPerl6 can be downloaded from the Pugs repository:
$ svn checkout http://svn.pugscode.org/pugs pugs
$ cd pugs/v6/v6-MiniPerl6
