`eval` works at global scope, so it cannot create local variables inside a function, no matter what you do. There’s some related discussion in [Unpack named tuples (does anyone know how to do it?) - #9 by rdeits](https://discourse.julialang.org/t/unpack-named-tuples-does-anyone-know-how-to-do-it/32456/9) .

Can you pass an anonymous function instead of an expression? That should be more flexible and _much_ more efficient.
