Unfortunately, I don't think that would work, as the signature requires `[B
>: Byte]`. `B` could be `Any` and in that case we need the slow implementation
that falls back to `Object.equals` 😕
Code example:
```scala
case class MyByteSeq(data: List[Byte]) {
def fastIndexOf(byte: Byte): Int = data.indexOf(byte)
//def indexOf1[B >: Byte](x: B): Int = fastIndexOf(Byte.unbox(x)) // This
won't compile
def indexOf2[B >: Byte](x: B): Int =
fastIndexOf(Byte.unbox(x.asInstanceOf[Object])) // This can fail at runtime
def indexOf3[B >: Byte](x: B): Int = x match {
case b: Byte => fastIndexOf(b) // I think the pattern match already
unboxes it
case _ => ??? // I can't call fastIndexOf here, so I need a duplicated
version of the code anyway
}
}
```
