For some reason, the `arrow=true` argument doesn’t seem to have any effect once I give `plot` a three-dimensional line. Is this a bug, or intended behaviour? Is there a way to get arrow heads in 3D, without having to resort to the (imo) more convoluted `arrow` or `quiver` functions?

```julia
plot([0, 1], [0, 1], arrow=true, linewidth=2, label="")

```

```julia
plot([0, 1], [0, 1], [0, 1], arrow=true, linewidth=2, label="")

```
