This question essentially revives [this older topic](https://discourse.julialang.org/t/correct-use-of-requires-jl/10493).

I dislike long loading times for modules that I use fairly interactively. Let’s say I have a `module A`, and a single (or very few) function `fB` in `A` depends on another `module B` which takes a long time to load. `Requires.jl` is one way to deal with that, but the user would have `import B` before being able to use `A.fB`. This is ok but not great. Is there a way to `import B` automatically on the first call of `fB`?
