Actually, it *does* automatically convert the static array to a slice.
Which is actually a bug, because you get problems like this:
int[] func() {
int[5] data = [ 1, 2, 3, 4, 5 ];
return data; // implicit conversion to int[]
}
void main() {
auto data = func();
// Oops: data now references out-of-scope elements on the stack.
// Expect garbage values and stack corruption exploits.
}
