Niko Matsakis	2b67d88809	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	2013-01-28 10:01:59 -08:00
Tim Chevalier	96b4f43675	Handle region errors where the actual scope is a statement ... Prevents a case of "unknown scope, this is a bug". I judged this too small to review. Closes #4500	2013-01-19 17:06:36 -08:00
