Here is the MWE:

```julia
module mmm # DEVELOPER WRITTEN: note NO explicit exports
"""
The "exported" function from this module is `publicfun`.
"""
function publicfun()
    println("in publicfun()")
end
function _privatefun()
    println("in _privatefun()")
end
end

```

```julia
module mmm_API # USER WRITTEN
# As one of the users who use `mmm` a lot from the REPL, I want to do `using mmm_API` 
# to get implicit access to both the public function 
# and the private function from the module `mmm`.
using mmm: publicfun, _privatefun
export publicfun, _privatefun
end

```
