Implicit enum conversions are a stupid PITA

Here's a Java 5 version with D-like syntax: 

enum Flag {
    READ  (0x1), WRITE (0x2), OTHER(0x4)
    
    const int value;
    private this (int value) {
        this.value = value;
     }
}

 int main(string[] args) {
    foo(FLAG.READ.value);
    foo(FLAG.READ.value | FLAG.WRITE.value);
    return 0;
}

No conversions required.
