Syntax error on enum

[greg0ire]

Weird issue that I cannot reproduce on https://psalm.dev/r/b10ef1cbd6 : https://github.com/doctrine/lexer/actions/runs/3664018448/jobs/6194159893#step:6:54

ParseError: Syntax error, unexpected T_STRING on line 7

Why is Psalm having an issue with enums? I'm using version 5.1.0

I found these snippets:

https://psalm.dev/r/b10ef1cbd6

<?php

declare(strict_types=1);

namespace Doctrine\Tests\Common\Lexer;

enum TokenType
{
    case INT;
    case OPERATOR;
    case STRING;
}

Psalm output (using commit ef02ded):

No issues!

Make sure nikic/php-parser was also updated to the latest version

$ composer outdated
Info from https://repo.packagist.org: #StandWithUkraine
Color legend:
- patch or minor release available - update recommended
- major release available - update possible

Direct dependencies required in composer.json:
Everything up to date

Transitive dependencies not required in composer.json:
phpstan/phpdoc-parser 1.13.1 1.15.0 PHPDoc parser with support for nullable, intersection and generic types

Almost everything seems up to date. I'm still using PHP 8.1 though.

Target PHP version: 7.1 (inferred from composer.json)

Maybe this is the cause?

EDIT: changing that indeed makes the issue disappear 🤔

Closing, I think that's expected, I should be using phpVersion=8.1 (right? if yes, sorry for the disturbance and in any case, thanks for the help)

And to reproduce it on psalm.dev you could add ?php=7.1 to the URL: https://psalm.dev/r/b10ef1cbd6?php=7.1

Good to know! Thanks!
