This has been discussed before, for example [here](https://discourse.julialang.org/t/is-there-a-with-operator-or-usage-pattern/52693/11) and [here](https://discourse.julialang.org/t/unpack-named-tuples-does-anyone-know-how-to-do-it/32456).

My impulse is to accomplish something like this with function keywords, e.g.

```julia
julia> t = (a=2, b=3)
(a = 2, b = 3)

julia> foo(;a, b) = a + b
foo (generic function with 1 method)

julia> foo(;t...)
5

```
