Dear all,  
moving to Julia 0.7/1.0.2 brings in some problems with old code I have.  
This time I have a user-defined module containing a fcuntion. This module is stored in a separate file MyMod.jl which I can acces as its location is in LOAD\_PATH. The simple exemple is

```julia
module MyMod
   export f1
   function f1(x) = x*x
end

```

Now in my Jupyter notebook I just have

```julia
using MyMod #loads correctly

function f2(x)
   z = zero(10)
   for i in 1:10
      z[i] = f1(rand())
   end
end

```

…but then it complains of now being able to use f1() stored in the module.  
I’m 100% sure that this is a scope-related issue, since function f2() can not reach f1() from the module.

Can somebody tell me what do I have to do to make function f2 reach function f1 from the MyMod module?

Thanks in advance,

Ferran.

Are you sure? There is an `end` missing.
