I think that need to be feature request for nikic/php-parser

[TomasVotruba]

I already asked in php-parser last week. This will most likely require php-paser 5, PHPStan 2 and then Rector 2 due to BC breaks.

I created downgrade PR rule first:

• [DowngradePhp84] Add DowngradeNewMethodCallWithoutParenthesesRector rector-downgrade-php#253

to allow code to be downgraded on the first place.

This will most likely require php-paser 5, PHPStan 2 and then Rector 2 due to BC breaks.

@samsonasik it seems to me that these criterion are now met. Is there anything more needed to create this new rule ?

[samsonasik]

The no parenthesis syntax is not only on method call, but also static call, property fetch, etc, per rfc

https://wiki.php.net/rfc/new_without_parentheses

which downgrade need to be exists first so full feature downgrade need to be exists first to avoid flip-flop lookup.

I am not fan of this syntax sugar, but feel free to create PR if you're interested, always start with improving downgrade part, there is starting point you can look:
