I tested the performance of an array of tuples and structs in Julia 1.3.1 and 1.5.1 and am a bit confused about the results. There are eight separate times based on three choices: 1.3.1 vs 1.5.1, structs vs tuples, and mutable member vs no mutable members. Briefly: 1.5.1 is much faster than 1.3.1 …

Yes, it sounds like that’s only applicable to Julia < 1.5.
