Emit semantic tokens for user defined conversions

Feature Request

User defined conversions are the only operator overloads that aren't able to be syntax colored to make them more obvious (aside from new and delete, which I reported recently).

I'd like to request semantic tokens to enable syntax highlighting when a user defined conversion is invoked.

The tricky bit is, which token should it be? On the parentheses? Sometimes there aren't any parenthesis.

Perhaps it should be a modifier on the variable being converted? Can we do that if it's an entire expression? Maybe then we could underline the expression without changing the color of the entire thing.

It would also be nice if "go to definition" worked for the conversion, like other operator overloads. But I don't know if that's feasible.

Commencez par examiner comment l’extension émet actuellement des semantic tokens et prend en charge go-to-definition pour les autres surcharges d’opérateurs C++. Comparez les exemples de conversion signalés, y compris les cas sans parenthèses, et déterminez une représentation de token qui puisse être appliquée de manière cohérente. Le travail sera considéré comme terminé lorsque le comportement, le choix du token et toute prise en charge de la navigation vers la définition seront spécifiés et couverts pour les formes de conversion pertinentes.
