I for one understood that B.jl and A.jl aren’t packages that are importing each other, but your post is legitimately confusing because it keeps mentioning packages and how you’re `using` them. You don’t describe the change to A.jl or what automatic changes you’d expect in B.jl, and it’s not apparent where compilation and benchmarks factor into this. Some phrasings are unintelligible: we `include` a .jl file, not a function; we can’t call .jl files; methods are compiled and packages are precompiled, .jl files are not.

If you don’t describe your problem as clearly as sijo’s step-by-step example does, then nobody can attempt to explain it. Here are some guidelines to help your readers follow along:
