you [...] aren't allowed to mutate objects that are in collections
Where is that documented? I've been doing this without consideration
and nothing's blown up yet.
How is a method to know if an object it's been passed is in a
collection? Equally how are you to know if a method is going to mutate
an object's properties?
You simply can't determine either situation conclusively. If this is
so fundamental, why haven't I been tripped up by it?
