Hi,
I was looking for a function, which gives the global variables available within the scope?
Is there such a function.
Thanks.

```julia
help?> whos
search: whos print_with_color
whos(io::IO=STDOUT, m::Module=current_module(), pattern::Regex=r"")
Print information about exported global variables in a module, optionally restricted to those matching pattern.
The memory consumption estimate is an approximate lower bound on the size of the internal structure of the object.
```

I have one question though.
```nohighlight
module DFT
global a
export f
f()=44
end
whos(DFT)
DFT 1540 bytes Module
f 0 bytes DFT.#f
```
why is :a not present in the output?

~~Each module defines its own, separate scope: [https://docs.julialang.org/en/stable/manual/variables-and-scoping/#Global-Scope-1.~~](https://docs.julialang.org/en/stable/manual/variables-and-scoping/#Global-Scope-1.~~) Edit: I misread. I guess `whos` chooses to only display exported variables, as stated in its doc: “Print information about exported global variables in a module”.
