There's a big difference between a function and a function

Could you please clarify in this context?
`Fun` is basically generated by code like that:
```d
extern (Windows) void* GetProcAddress(void*, const char*);
auto fn = cast(T)GetProcAddress(lib, mangledName.toStringz);
```
If it is a function, you get its address with the & operator.
But if it is supposed to be a function pointer, something is
wrong with the declaration...
I have no idea what the correct term is but the debugger says
`fun` is:
(if that `assert()` is removed and it compiles):
```
Type: void function(...)*
Value: 0x0000000000000000 null
```
I can get some address with `&fun` but deferencing then fails:
```d
auto addr = &fun;
assert(*addr); // Error: expression `*addr` of type `extern (C)
void(...)` does not have a boolean value
```
