I use it in one-liners like the following:

```julia
x = (3, "TEMP") # in real code `x` comes from an user terminal input function, which can return nothing

!isnothing(x) && (begin n, dir = x; end)

```

I just remembered one interesting example from [this other post](https://discourse.julialang.org/t/use-condition-result-inside-conditional/52893/6), by the way, which I rewrite here for reference:

```julia-auto
foo() = 3
!isnothing(begin x = foo() end) && println(x)

```
