Description Daniel Bates 2018-10-29 11:40:47 PDT
Consider the following enum:

enum Flag {
    A = 1 << 0,
    AAlias = A,

Pretty-printing OptionSet<Flag>(Flag::A) prints the last-most enumerator with value 2, AAlias. But I propose that it print the first enumerator with value 2, A, because aliased enumerators tend to be used in bounds check as opposed to actual set members.
