Is it legal to have a function taking two aliased slices?

Example:
    void process(float[] input, float[] output)
    {
      // do stuff
    }


I'd like to sometimes have overlapping slices, and don't want the compiler to assume they do not overlap.

Yes, it's legal, and the compiler doesn't assume anything about the two slices, including whether they overlap or not.
