Tinker is a very basic REPL - it has no readline support or error handling - so I've just made a package to add Boris support to Laravel 4.

I can't find anything named tinker in the latest laravel source. Where did you find it?

I can't find any documentation and haven't tested it yet but here's a class for a 'tinker' command in the Illuminate (Laravel) sources: https://github.com/laravel/framework/blob/master/src/Illumin...

'php artisan tinker' on the command line should bring it up.
