I've just added a small tie() example to the perlito5-in-the-browser page.

This was implemented today, and it only supports a few methods for now.

tie() does not make perlito5 any slower - the tied containers use a separate class, while the non-tied perl5 containers are javascript native array and hash objects.

Perlito5 is an ongoing implementation of perl5, with a javascript backend. The compiler is written in perl5. It compiles itself to javascript, so it can run in a browser.

The test suite can be run with node.js. It now passes 288 tests. About a hundred of these tests are from the official perl5 test suite.

There is a new article about the Perlito Perl 6 compiler, published by the São Paulo Perl Mongers. The article is mostly focused on the Javascript backend, and all code snippets can be run in the browser. There are also instructions on how to install the Perl 5 backend from CPAN. The article finishes with an overview of the compiler internals.

In the development front, Perlito now passes all it'…
