I have a function f() = (a=1, b=2, c=3) , and I can pick out one of the returned components of the tuple as julia> f().a 1 Can I select in this way a and at the same time c? In other words, I would like to get a, c = f()???.

Only works for Julia \geq 1.7 though

Actually, I realized I would really like to be able to collect the results in variables whose names are not the same as those in the named tuple. For example: myvar = f().c. But with an arbitrary multiple selection, myv1, myv2 = f()... (let us say, a and c). Can this be done?

OK, found this: julia> v1, v2 = f()[[:a, :c]] (a = 1, c = 3) …

julia> f() = (; a=1, b=2, c=3, d=4) f (generic function with 1 method) julia> x, _, _, y = f() (a = 1, b = 2, c = 3, d = 4) julia> x 1 julia> y 4

Nice! What I’m not so happy about is that one has to know the order in which the arguments have been returned.
