Couldn't this be done without collecting?
the object trait matches the required trait during trait selection. The existing code was checking that the object trait WOULD match (in a probe), but never executing the match outside of a probe. This corrects various regressions observed in the wild, including issue rust-lang#26952. Fixes rust-lang#26952.

Time to remove a thousand clone calls :P.
@huonw @Manishearth How about a lint against calling .clone() on a Copy type?

Correct regression in type-inference caused by failing to reconfirm that the object trait matches the required trait during trait selection. The existing code was checking that the object trait WOULD match (in a probe), but never executing the match outside of a probe.
