Is there a variable within a function that will return all function arguments as a named tuple (or something similar). Would be useful when calling a second function, that uses a similar set of arguments.

```julia
f2(; a,b,c ) = a+b+c

function f1(; a, b)
    c=a+b
    f2(; c, AllArgs... )
begin

```

You can use slurping (documented [here](https://docs.julialang.org/en/v1/manual/faq/#The-two-uses-of-the-...-operator:-slurping-and-splatting)):

```julia
function f(; vars...)
    println(vars)
end

```

yielding

```julia
julia> f(; a=1, b=2)
Base.Pairs(:a => 1, :b => 2)

```

EDIT: for example:

```julia
f2(; a, b, c) = a + b + c

function f0(; vars...)
    c = vars[:a] + vars[:b]
    f2(; vars..., c=c)
end

```
