That’s totally reasonable to hope for, but it won’t work precisely because the suggested code, even if written out by hand, still doesn’t work (it creates global variables, not local ones, because that is inherently how `@eval` always works).

The only way for `@unpack params` to work would be for the type of `params` to be known when the `@unpack` macro is expanded, but that’s impossible: if you’re inside a function, the macro will be expanded before the function is run and therefore before `params` has a value.
