`impl<A, B> FromIterator<(A, B)> for (Vec<A>, Vec<B>)`?

Recently /u/shortstomp asked on Reddit about this example.

The impl seems useful to me and I'm willing to implement it (possibly with more fields, e.g. A..J) if it's considered a good idea.

I've never tried hacking std, so why not try it? :)

This is pretty much rust-lang/rfcs#870 rust-lang/rfcs#930.
It would be really nice to revive that RFC as a part of the ergonomic initiative.

[Kixunil]

Yeah, this is practically the opposite of rust-lang/rfcs#870.

Going to go ahead and close since I think this would need an RFC, see rust-lang/rfcs#930 for the RFC tracking issue.
