Is this the right way to specify operations in xcore?
Getting a syntax error at line 12, "mismatched input 'op' expecting '}'".

enum DaysInWeek{
    MON
    TUE
    WED
    THU
    FRI
    SAT
    SUN
    
--> op boolean isWeekend(DaysInWeek daysInWeek) {
        switch(daysInWeek){
            case SAT, SUN:
                return true
             default:
                return false            
        }
    }
}

In ecore/genmodel - one would add methods to the generated enum file without the @Generated annotation.

Is there a bug in my syntax or is it something that xcore does not support currently?

Thanks for the help

You can't specify operations for enumerations. Not only doesn't Xcore
support it, but neither does Ecore and that's what ultimately drives the
generator...
