Of course this `assert()` is actually inside `static this()` and 
there is only one declaration. I just want to show that the used 
symbol and call is the same.

Also this is **working** code. I just put the `assert()` there to 
ensure the function isn't called by a race condition before it 
was loaded (module constructors often have cyclic dependency, so 
I cannot put this in a more clean way).

Those asserts() are set in:

module A: module constructor
module B: some function

To also anwser to Adam: no, this symbol is unique. The first line 
of the error says:

```
Error: function `a.fun(string param)` is not callable using 
argument types `()`.
```

**Note that I have changed the actual module name and signature, 
it has orginal 5 arguments and very long names.**

The point is, it shouldn't be called in this line anyway?
