Maybe I am seriously misunderstanding the documentation, but this does not seem to work, nor is it the way core Makie creates its recipes, e.g. in https://github.com/JuliaPlots/Makie.jl/blob/8146f27ffa86d70a6aba786353ddc89f4d8b136d/src/stats/boxplot.jl#L34

The (presumably) incorrect docs confused me for the last half an hour. Hopefully this saves others from the same confusion :D
