psysh: Parse errors when using namespaced classes/functions

I’m getting this really weird bug, since I’ve upgraded my Laravel version to 7.x (Laravel Tinker v2.4.2). The shell doesn’t accept me using FQCNs anymore. See the output below:

Psy Shell v0.10.4 (PHP 7.3.20-1+ubuntu18.04.1+deb.sury.org+1 — cli) by Justin Hileman

=> "User"

Even running psy\info() doesn’t work:

>>> psy\info()
PHP Parse error: Syntax error, unexpected ')' on line 1

I get the same error locally, in a docker container and on our server. I have no config files for psysh, but maybe Laravel adds some configuration through Tinker out of the box.

Do you have any idea how I can fix this?

Sadly, the same result:

php artisan tinker --execute="App\User::class"

It’s really weird you can’t reproduce the issue. Of course we have a ton of code and external dependencies, so those could also influence the code. For now I have a solution: use v3.* of php-parser. Thanks a lot for your time and help!

Thanks for checking @ikari7789! I was already on v4.9.1 of nikic/php-parser, but I did try to downgrade to v3.1.5 and that solved the issue. Apparently there’s a bug in v4.* somewhere.

Thanks again for your help @ikari7789 and @bobthecow!
