I'm getting started with a Laravel 5 project and trying to run some experiments using 'php artisan tinker' (psy shell), but I'm running into some weirdness.

The PHP REPL does not implement readline's line editing and history capabilities. I don't know if there's a PHP module that implements it, but you can do:
rlwrap php artisan tinker
You may have to install rlwrap for your OS.
