In the new pre-release version of AL Language, there is a new “IS” operator, ready to be used, but for now very limited.

Microsoft has confirmed that “IS” operator is coming for Interfaces but it’s also possible to expect in future to be expanded soon like this:

What do you think about this new operator?

Stay tuned for more information! 🚀
