@save "foo.jld" doesn't save anything instead of saving everything inside a module

Julia 0.5, Windows 7, latest version of JLD,

@save "foo.jld"
d = load("foo.jld")
Dict String -> Any with 0 entries

When I use @save "foo.jld" a, it does save a.

In the code snippet above, you don't define any variables before you call @save, and so @save doesn't save any variables.

Also note that, if you do not specify any variable names, @save will save all global variables, but not any variables local to the current function.

For sure I have a bunch of variables before I call @save. I just didn't put '...' here. I am aware that I am not going to save an empty module.
And I want that to save all global variables inside a module. It is not inside a function. I call it globally under a module.

Can you provide some code that reproduces the issue?

@simonster Sorry I didn't reply quickly.
Yes, here's what I tried, under my current environment.

`
module foo
using JLD
a = 1
@save "foo.jld"
d = load("foo.jld")
end

`

And d is a dictionary with no entries. Instead if I use @save "foo.jld" a, then d has entry a.

Thanks, that's very useful. It seems that @save currently saves only exported variables from modules other than Main. Perhaps we should change this.

I see. Then that's the way I am using the function is not correct.
Since description of this function says "save the variables like Matlab saving workspace". I was thinking maybe saving inside module is similar.
