vec.rs has too many `position`s

[jld]

A simple program:

fn main() { [0].position(|x| true); }

The result:

position.rs:1:12: 1:35 error: multiple applicable methods in scope
position.rs:1 fn main() { [0].position(|x| true); }
                          ^~~~~~~~~~~~~~~~~~~~~~~
position.rs:1:12: 1:35 note: candidate #1 is `core::vec::__extensions__::position`
position.rs:1 fn main() { [0].position(|x| true); }
                          ^~~~~~~~~~~~~~~~~~~~~~~
position.rs:1:12: 1:35 note: candidate #2 is `core::vec::__extensions__::position`
position.rs:1 fn main() { [0].position(|x| true); }
                          ^~~~~~~~~~~~~~~~~~~~~~~
error: aborting due to previous error

I think this is a conflict between impl<T:Eq> ImmutableEqVector<T> for &[T] and impl<A> iter::ExtendedIter<A> for &[A]

(Also, the error message is not maximally informative.)

Reproduced 2013-06-05, agree it's properly tagged and milestoned.

The position/find functions are now provided by std::iterator (with an underscore as a method resolve bug workaround) so I'm going to remove all forms of position and find from vectors.

Fixed.
