Error "Class properties must be methods"

[Hanspe-3019]

With esversion: 8 or higher, I get this error message:

Class properties must be methods, Expected '(' but instead saw '='

Sample:

class Demo {
    static staticProperty = 'A';
}
console.log(Demo.staticProperty);

Script runs as expected, yielding 'A'.

Thanks for taking the time to file an issue! The language feature you are looking for is called "numeric separators", and if you search this project's issue tracker for that term, you'll find a corresponding feature request. In order to keep things organized, I'm going to close this issue as a duplicate.

This doesn't appear to have anything to do with numeric separators...but the link to class fields is correct, I guess.
