Are the problems surrounding slicing static arrays easily explainable?

>From my point of view (fairly new to the language) it's confusing that you can
pass a dynamic array to a Range-based function, while you'll need to slice a
static array if you want to pass that data to a such function.
To me it seems more user friendly if you could pass even static arrays to such
method, but I presume there's a good reason why this is avoided. I haven't
quite managed to figure out this yet, any pointers would be appreciated.
