There's a hack to make static slicing working actually.
I've used it once to make a kind of set of character. Reduced
example:
```
struct Foo
{
static auto opSlice(int index)(size_t lo, size_t hi)
if (index == 0)
{
return 42;
}
static auto opIndex(A...)(A a)
{
return 42;
}
}
static assert(Foo[0..1337] == 42);
```
I don't know if it is possible by error, maybe they forgot to
disable this form of slicing.
