In python I could do this and the result will be as follows

```python
>>> a, b, *c, d = [1, 2, 3, 4, 5, 6]
>>>a
1
>>>b
2
>>>c
[3, 4, 5]
>>>d
6

```

I know there’s unpacking in Julia and know how to use it. But the part where I can pack multiple values into `c` as I did in python here is were I can’t figure out yet.

Have any idea?

[here](https://app.slack.com/client/T68168MUP/C67910KEH/thread/C67910KEH-1657898495.843949) a rough workaround.

```julia
julia> macro splatin(e)
           pos=findfirst(el -> !(el isa Symbol), e.args[1].args) 
           L=length(e.args[1].args)
           permute!(e.args[1].args,[1:pos-1...,pos+1:L..., pos])
           R=length(e.args[2].args)
           permute!(e.args[2].args,[1:pos-1...,pos+R-L+1:R..., pos:pos+R-L...])
           return esc(e);
       end    
@splatin (macro with 1 method)

julia> @splatin (a,b, c..., d) = [1,2,3,4,5,6,7];

julia> a,b,c,d
(1, 2, [3, 4, 5, 6], 7)

```

Nice macro, but shouldn’t it be called `@slurp`? Splat is the opposite operation.
