> DTrace was designed with maps-only for a reason. You write this like you are implying that the DTrace designers somehow foresaw that spectre would be a thing and therefore array accesses would be a risk. This is obviously false. I’m sure there are reasonable reasons to not have arrays but predicting spectre 10 years before it was found is not one of them.
