ref parameter qualifier and static arrays

[Paul via Digitalmars-d-learn]

Is it possible to call a function like this...

void foo(ref int[] anArray)

...with slices of static arrays? I thought I might be able to use 
[0..$-1] but to no avail - I get an error like this (which is 
confusing!):

(ref int[] anArray) is not callable using argument types (int[])

I've modified the function declaration and used .ptr when calling 
it but it seems like a retrograde step for a modern language - 
although I suppose ref is pretty much the same thing.

In practice I'm using arrays of structs (which are of various 
fixed sizes and known at compile time) that are currently global 
in scope - something that I'd like to avoid.

I suppose I could just ask, what is the 'best' way to give access 
to variously sized static arrays between different modules?
