First, please [quote your code](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530).

I your problem truly has this simple structure, then I would guess that compile time would be dominated by O(1) factors; since there is nothing to infer. Also, a global `A` may be the source of most of your performance problems at runtime.

But why aren’t you using something like

```julia
(kwarg1 || kwarg2 || ...) ? A : nothing

```

or even

```julia
dummy(; kwargs...) = any(values(kwargs)) ? A : nothing

```
