// A comptime-constructed enum (declare/define) with two same-named variants is
|
|
// rejected loudly. Two `value` variants would make construction (`.value`) and
|
|
// matching ambiguous — `define` bails naming the duplicate, instead of silently
|
|
// minting a malformed enum that picks one arbitrarily.
