I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I have over 7 years of experience in backend development, primarily using Go. While my expertise is in building robust backend systems, I’m currently learning Cairo in Dojo Coding and am eager to apply my skills to contribute effectively to projects using this language.

@juankohler what's the status of this?

[enitrat]

@ClementWalter the Language Server has some issues with procedural macros (they're undetected so considered as errors) - as such I don't want to merge it yet, I reported the issue and proposed them to simply mute diagnostics for macros.
