"use" Keyword for traits treated as error

[bbak]

The use keyword for traits leads to an error.

PHP Intellisense Version 1.5.0; VS Code Insider, updated today.

Hey @bbak,

We did a quick check and this issue looks very darn similar to

• #447 - Is there some way to disable log messages?
• #446 - show whole variable declaration
• #445 - Formatting crashed

This could be a coincidence, but if any of these issues solves your problem then I did a good job 😄

If not, the maintainers will get to this issue shortly.

Cheers,

The parser has a problem with things named with reserved words, even though it's ok here.

I filed microsoft/tolerant-php-parser#165 for this

[bbak]

Any progress on this? More and more PHP Code uses traits, so that the Problems View is more or less unusable, since the keyword use inside a class is seen as an error that leads to dozens of follow-up errors, so that the 99+ Errors boundary is reached quite quick.

From my understanding, it's unrelated to Issue 165 in tolerant-php-parser. It is just an additional use case of the existing reserved keyword use.

@bbak accepting PRs ;)
Pretty sure it needs to be fixed in the parser though

This is not a problem with 'use' as such, but 'Object' being an illegal namespace-identifier as of php-7.2, not? We use namespaces quiet a lot in our codebase, without the language server tripping over it -- but if I add 'object' as namespace-identifier in a use-statement, the error as shown above is thrown.

Edit: https://secure.php.net/manual/en/reserved.other-reserved-words.php:

The following words cannot be used to name a class, interface or trait, and they are also prohibited from being used in namespaces. object (as of PHP 7.2)
