Hello,

I am a little bit confused, is this supposed to work some how? When a function returns a tuple, can I somehow add each element of this tuple to a separate variable without temp allocations? Something like this:

```julia
f(x) = 2x, 3x

A = 1 
B = 2 

A, B .+= f(3)

```

I expect `A = 7` and `B = 11` afterwards.

Thanks

This is  
`A,B .= (A,B) .+ f(3)`  
but the RHS already returns a Tuple, so `.=` is wrong. What you want is:  
`A,B = (A,B) .+ f(3)`

Thanks, I have forgotten to answer to you. It does not look that concise but of course this syntax is consistent with what I want it to do 😉
