I have several matrices `x1, ..., xn` what’s a way to create a named tuple `(x1=x1, ..., xn=xn)` without having to type all components one by one?  
For example:

```julia
x1 = rand(2, 2)
x2 = rand(2, 2)
x3 = rand(2, 2)

lazyhelper(x1, x2, x3)
# returns (x1=x1, x2=x2, x3=x3)

```

Just:  
`(; x1, x2, x3)` (needs Julia 1.6)

If you want to automate it for a large number of variables, you’ll either need to define a macro or create an expression and `eval` it.

I have a package [AddToField.jl](https://github.com/pdeffebach/AddToField.jl/) that makes the creation of a named tuple easier as well

```julia
@addnt begin 
    @add m1 = ...
    @add m2 = f(m1)
end

```
