I wanted to avoid activating it globally

Feel free to try to get it to work

OK I'll try later!

but FYI:

@setup example1

is used to configure @examples, not doctests; that's why it didn't work.

On a different note, using # hide notation won't work in the sense the code will run but it won't be hidden -- that's syntax from Literate.jl package and we are not liberating the docs; only examples.jl

Didn't work
