No animals were harmed

[stellentus]

After the "No animals were harmed slice" it would be interesting to see a slide that changes 'hungryCat[0]' and shows that the original animal slice was modified.
One of the students asked about this.
This is a very important warning for working with slices. I think it often trips up new users.

Mutation came up in "Mutation happens" but it might help to reference it earlier as well.

Is there a copy function for slices? It could be referenced here, too?

The "change capacity" discussion was done live but it would be nice to see it in a slide so students (and future teachers) can refer to it.

I think more slides showing mutation problems could be helpful... or just really, really confusing. Probably just confusing.
