Slicing vectors with negative indices returns wrong result

[AmesingFlank]

Consider this code segment

@ti.kernel
def k(i:int):
    x = ti.Vector([i, i+1, i+2])
    print(x[:-1])

k(0)

it prints out

[]

I don't think we ever supported "-1" in either indexing or slicing. Shall I convert this issue to a feature request then?

That makes sense. The reason it felt more like a bug than a missing feature was that there was no warning messages. Notice that I didn't enable dynamic indexing, so the index is a compile-time constant and the compiler should be able to produce a warning about it being negative, yet it did not.
