RFC #10: Should bitmask enums be added?

[ProCode-Software]

These would allow for multiple enum items to be applied as a single value, with efficient O(1) item detection. Algebraic enums or items with parameters aren't allowed.

• Example of bitmask types in Go:

  type MyEnum uint8
   const (
      Option1 MyEnum = 1 << iota
      Option2
      Option3
  )
   var myValue MyEnum = Option1 | Option3
   // Check for an option
  (myValue & Option3) != 0
   // Assign an option
  myValue |= Option2
   // Remove an option
  myValue &^= Option1 // JavaScript: myValue &= ~Option1
