I use it in one-liners like the following:
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, by the way, which I rewrite here for reference:
foo() = 3
!isnothing(begin x = foo() end) && println(x)
