> Is it possible to splat into `@ccall` ?

You can splat into the AST which `@ccall` is a part of, provided you do it before macro expansion. For example:

```julia
@eval @ccall printf("%d %d %d %d %d\n"::Cstring, $((:($i::Cint) for i in 1:5)...))::Cint

```

But it’s unlikely that it’s a good idea to use `@eval` like this! What’s your surrounding code look like for this use case?
