Discard elements of function output?

[fredrikpaues]

In MATLAB, I would write [~, two] = function_with_two_outputs() to discard the first of two function outputs. Is there a syntax for doing the same in Julia? That is, discard one or more elements of the tuple returned by a function?

I guess that an alternative would be to do two = function_with_two_outputs()[2]. Or is that a bad idea for some deep (or for that matter shallow) reason?

Not super discoverable I admit, but this discussion was had before here:

My wishlist for the next version of Julia

As a Matlab person who recently switched over to Julia, below are some items on my wish list. Many thanks for your consideration! Creating a m x n sized NaN should be as simple as NaN(m, n). Right now, I have to do this: A = fill!(Array{Float64}(undef, m, n), NaN); If I have two 1-column data with the same size, A and B, I should be able to get an Index by Ind = A>3 && B<15. Right now, I would have to use map function to broadcast first: Ind = map(A, B) do a, b a>3 && b<15; end…

If you go through this thread you’ll see most of it is about whether (and how) this is possible in Julia.

In Julia you’d just write _, two = function_with_two_outputs() (_ cannot be read from again). nargout shenanigans aren’t easily possible though.
