Glad to see this. Moving out of * is scary. |

@brson thanks for the quick review. this seems like a patch that has very few "substantive" changes (two lines) but is very prone to bitrot ... :) |

…opy bound. Consider: T:Copy could be bound to ~T, which is not implicitly copyable.
…ed-on-type, since it creates moves that were not apparent. It also turns out to be not widely used.

…-generics, r=brson Two changes: 1. Make type parameters move by default, even if they have a Copy bound. After all, they could be bound to `~T` or `~[]`. Also, this is a necessary step towards removing `copy` keyword and replacing with clone. 2. Make it illegal to move from `*T`. This is dangerous in a "moves-by-default" scenario, because it's very easy to move when working with a `*T` pointer. Also, it requires zeroing memory, which we hope to do away with someday.
