The evaluation order of some things is [undefined](https://discourse.julialang.org/t/chained-comparison-evaluation-order/8999/3) (or at least it was), which does leave open possiblities. For example, in

```julia
res = f(x) < f(y) < f(z)

```

the `f` calls could be evaluated in parallel if results don’t depend on their order. Guy Steele [stated recently](https://youtu.be/c_ZJECVlpog?t=420) that one of the lost features of Fortress he would like to see continued in modern parallel languages is “parallel by default”, where it would require a little effort to make things sequential where needed, rather than requiring a little effort to make things parallel.
