Interesting... looks like the collect method is missing this possible case for tupleTpe:

enumeratum/macros/src/main/scala-3/enumeratum/ValueEnumMacros.scala

Lines 188 to 241 in f9b528a

tupleTpe match {
case '[TakeHead[h, tail]] => {
val htpr = TypeRepr.of[h]
(for {
vof <- Expr.summon[ValueOf[h]]
constValue <- htpr.typeSymbol.tree match {
case ClassDef(_, _, spr, _, rhs) => {
val fromCtor = spr
.collectFirst {
case Apply(Select(New(id), _), args) if id.tpe <:< repr =>
args
}
.flatMap(_.lift(valueParamIndex).collect { case ConstVal(const) =>
const
})
fromCtor
.orElse(rhs.collectFirst { case ConstVal(v) => v })
.flatMap { const =>
cls.unapply(const.value)
}
}
case _ =>
Option.empty[ValueType]
}
} yield Tuple3(TypeRepr.of[h], '{ ${ vof }.value: A }, constValue)) match {
case Some((tpr, instance, value)) =>
collect[tail](instance :: instances, values + (tpr -> value))
case None =>
report.errorAndAbort(
s"Fails to check value entry ${htpr.show} for enum ${repr.show}"
)
}
}
case '[EmptyTuple] => {
val allowAlias = repr <:< TypeRepr.of[AllowAlias]
if (!allowAlias && values.values.toSet.size < values.size) {
val details = values
.map { case (sub, value) =>
s"${sub.show} = $value"
}
.mkString(", ")
Left(s"Values for ${valueField.name} are not discriminated subtypes: ${details}")
} else {
Right(Expr ofList instances.reverse)
}
}
