Ok, this is already discussed [here](https://discourse.julialang.org/t/isapprox-for-array-of-tuples/18527) and [here](https://github.com/JuliaLang/julia/issues/18779) ( to sum up, it is preferred to leave explicit collecting if one want as is it not clear with a tuple if one want elementwise approximation, or approximation of the whole tuple)
