All number types implement Copy, which mean they are passed by value rather than by reference. I'm assuming that because all members of he tuple implement Copy, the tuple itself does too. Though wasn't aware it worked this way — would make sense tho.
Yup! This is what's known as Auto Traits! This is why you usually don't have to make a call to unsafe to try something impls Send and/or Sync
Hmmmm or maybe not. Maybe a tuple has a blanket Copy Trait impl if all items are copy
Heh, yeah this is what I suspected. Auto traits work for markers only afaik.
