Slicing a static array is the equivalent of taking the address of a local 
variable. It's a bug that it's not considered @system.

And IMHO, the fact that the language _ever_ implicitly slices static arrays is 
a major design flaw. It's the same as if passing a variable of type T to a 
function that accept T* implicitly took the address of that variable rather 
than giving an error, and I think that most people would agree that that's a 
dumb idea. Unfortunately though, I don't expect it to be fixed at this point, 
since it would break too much code to do so.
