You can’t do that. A macro cannot do more than you could by typing code. And you cannot define a module in `Y` and expect it to be in `X`. You could `eval` into any other module, as you found out in the [other thread](https://discourse.julialang.org/t/how-to-define-a-function-in-a-different-module-other-than-what-you-are-in-right-now/11736). But as stated there, that is bad style. I’m pretty sure that there is another solution to you problem though…
