FYI, remember that you often want to set `evals=1` when using `setup` with mutating functions in BenchmarkTools. See the discussion in [BenchmarkTools setup isn't run between each iteration? - #6 by rdeits](https://discourse.julialang.org/t/benchmarktools-setup-isnt-run-between-each-iteration/36258/6) and the manual section in [https://github.com/JuliaCI/BenchmarkTools.jl/blob/master/doc/manual.md#setup-and-teardown-phases](https://github.com/JuliaCI/BenchmarkTools.jl/blob/master/doc/manual.md#setup-and-teardown-phases)
