Rewrite the coercion code to be more readable, more sound, and to reborrow when needed. Regarding soundness: there was a subtle bug in how it was done before; see the compile-fail test for an example. Regarding reborrowing: reborrowing allows mut and const slices/borrowed-pointers to be used with pure fns that expect immutable data. r=brson 2013-01-22 17:20:08 -08:00			`trait Reverser {`
